I guess it doesn't do me much good to obsessively collect every new piece of IF if I keep it to myself and don't use it in some way. So I checked out Google Drive, plus a program to keep folders synched (many thanks for your help. Vaporware!), and, well, here it is.

Be sure to read the readme. Basically, this is a copy of my own collection, the way I organise it. Hopefully it'll be a reasonably-reliable backup for many games, and hopefully it'll be as complete as possible. It's not all sorted yet; the "Pending Games" folder is a repository for games I've yet to play and cathegorise. It's a slow process.
If you find that I've forgotten to take out any commercial game at all, or any commercial emulator, PLEASE tell me and I'll remove it at ONCE.
Now, short of posting this link in a bunch of places, I'm not sure where it would really belong. I'd like it to be proeminently available. I'd like for people to be able to say "Hey, guys, where I can find this game?" "Well, you can look in IFDB, the ifarchive or in this guy's Google Drive collection". I'm not quite sure how that would work. If anyone has any idea where the link could be posted for this to happen, I'd be grateful.
Cheers!
PS - ADRIFT games specifically are sorted into 3.80, 3.90, 4.xx and 5.xx games. Under "Tools and Interpreters" you'll also find the windows interpreters for each version. I hope they don't have to be actually installed; if they do, the files themselves probably won't be much use to you, I'm afraid!
