A way to share 1TB of photos with family

As a keen photographer for 30 years, have millions of photos (1TB worth).  All are in LR, most are tagged with keywords, some are processed, many are not (no time).

The problem I want to address is that if my wife wants to make a photo album, or my my daughters want to look through photos of their lives, there is no tenable way to do this.

Yes, I could spend man years go through all the photos, processing the good ones, and uploading them by event to a sharing site like smugmug, zenfolio etc.   This doesn't work for 3 reasons:

1. it looses all the keywords and search ability.
2. I have no time to do this (it will take man years)
3. If I upload an album of unedited (bad) photos, then later edit them, i have to find and update the web version, which is very manual and time consuming.

I tried this for a year, and gave up.

The problem is that photos are "locked" in lightroom, and light room is single user.

One solution is to for LR to use a multi user database (this is easy to implement with say mysql or similar), and then offer a read only LR viewer application which can access the lrcat file and photos on a shared drive or similar.

This will allow my family to search, view, download and make photo albums. Currently they have no way to do this, so none of my pics get seen by anyone except the 1% or less which I have time to publish to my zenfolio account.  In zenfolio, manually re-create the hierarchy in lue of keywords, e.g.:

1. people
2. holidays
   
3. weddings
4. events

Adobe have spent a lot of money making a tablet version of lightroom, but it is utterly useless for me and my family needs as:

1. There is no read only mode.  So I cant give it to my kinds in case they accidentally delete or edit the pics.  PLEASE MAKE A READ ONLY VERSION OF LIGHTROOM TABLE FOR FAMILY VIEWING!
2. It has no option to make photo albums.  In theory, it might be possible to download photos in LRM onto the ipad, them use them in a separate photo album SW, due to point 1 we have not tried this.
3. 1TB of photos would have to be uploaded to the web, then downloaded to the device, which is on the same network as the photos. This is crazy.
4. Only highly compressed version of the files are synced, not the originals (which would be needed for printing etc.

In fact, I cant see the use case for lr mobile in its current form, as I use my laptop for all editing, viewing and displaying on TV via HDMI as it has all my photos, the full lrcat, and all the features.  In its current form it has no use for me as the "owner/photographer", and no use for my family as I cant give them read only access.

My suggestions are:`

1. Add a paid-for integrate a web album, exactly like zenfolio. I.e. it allows you to mirror your collections folder hierarchy, preserves your key words, and allows hierarchical folder based permissions and inheritance.  This would make it FAR easier to publish pictures in a searchable manner, to a website, and auto-update pics when I later edit/process them.  My wife could make photo albums by downloading the pics she wants and using a 3rd party photobook SW.  Kinds could brows the web to see their pics (and share them as they wish).  Downside is having to upload 1TB of images, and having to groom them, but at least the process as a whole would be better than what is available now.
2. Make a read only version of lightroom mobile. This is a poor solution for family, but at least they can view some of the photos.
3. Make lrcat multi-user + read only versions of LR. One master, many readers would do for the family case.  But DB on a server would be awesome for two of us to work on the same photo library (e.g My wife and I)
4. Have a read only LR license. I could them give my wife a copy of the LR cat file and an external HD of the photos, and she could search, view, create photobooks etc from this.  

Each of the above are partial solutions, but any of them would help.

I love LR for the speed of editing, but HATE it for the fact that my 1TB of photos are locked in it, and my family only can see 1% i have had time to manually upload to my zenfolio account.

NOTE: the way I did it before LR was to have my photos and lrcat file on an external iSCSI mounted NAS. I named the photoshopped version of files the same thing with "a" at the end. I gave read only access to the dirs on the NAS to my family.   They then used google picassa to do their own keywording and management.

Now I have all the photos and lrcat file on a 2TB M.2 MVMe 960 pro internal SSD, and its far faster, but noone can search, browse or view the 1TB of pics.  Sadly, the pics are spread across 3 lrcat files, as 1 lrcate file grinds to a halt after about 300GB of pics are imported, but thats another issue.
