Nontroppo : thanks.
I’m abit in a hurry, but here are some thoughts…
First…I love QuickSilver...** The tagging possibilities you're showing are nice. They seem similar (in features only, must I emphasize...) to what I've seen from the new explorer/Desktop Search in Vista — meaning : more intelligent usage of metadata, and better integration. But Quicksilver seems to make the integration more fluid and useable. Can't compare right now though.
How much is that metadata portable though ? Is it strictly reserved to OSX and would be lost if read by windows or Linux? My experience with metadata fields for files is that they’re not that reliable and/or portable.
The new Tag2find is supposed to offer some kind of integration in explorer and other desktop search tools and launchers like farr (via some specific APIs) too. So, those with XP might be able to soon have a better system to tag files (with tag clouds, statistics, etc.). Still, all these solutions (including the one provided with QuickSilver / MacOSX ) leave me with the same feeling of "insecurity": how permanent is that metadata, that tagging, how portable is it, how robust is it?
Tagging stuff is as time consuming as naming files or classifying them in folders. If all that work is going to be lost by changing between Oss or just backing up, etc., it's not a perfect solution. Tag2Find is supposed to provide some solutions to keep trace of all tags in the the advent of data transfert… we’ll see.
(Nontroppo : in another you talked about the proprietary format of tag2find’s databas. Would you say the OS X format is not proprietary?)
If you look at my points in my first post, you'll see why I decided to include everything in file names -- maybe not very sexy and elegant solution, I’ll admit, but the only one I'm sure will pass the portability test relatively well. If I switched to Linux Or Mac OS tomorrow I’d be able to use my system as if it was native.
vixay : calling my script a script is actually probably a bit too much

. I’m mostly using AHKs text replacement capabilities.

I think the whole issue comes down to, how can we use our computers to be more intelligent and do things for us, rather than have us do things for the computer (so that it makes it easier for us later).
I always try of course to have my computer do things for me, of course… whether or not I succeed is another story.
So a database would be a good idea, as long as it was seamless, and didn't have me pulling out my hair!
I personally find problems with traditional databases. Especially when it comes to backup and portability (e.g. : it can be very annoying/infesable to have to backup a 50gb file every night). There might be ways I completely ignore, but from what I’ve seen…
AskSam, Ultra Recall, myBase, General knowledge Base, treepad, and others more PIMed, like Info Select etc., it’s pretty much always the same story.

... even if I genuinely do prefer Farr (go mouser go!!!

)... e.g. Farr has better file manipulation-browsing possibilities, the result view is more detailed, it'S very customizable, and it searches without an index by default -- a must for someone like me who messes with folders and files all the time.
QuickSilver also has some advantages (some are user friendliness, sheer beauty, speed, and great plugins) but none that I miss with farr. I won't go into a detailed comparaison of farr and quicksilver as it'S been months since my last intense quicksilver usage. But it could be fun if you'd do one! You seem like the perfect person for that.
