You'd
certainly be welcome to have the software and code.

You'd have to get the RFID kit (I've just looked and I can't bloody find the one I have on ebay any more - I was rather hoping to use the same readers and tags for the whole house).

Short of having 4 PCs in each room I am struggling to think of a way to narrow the search down - I'm sure I'll think of something though ;-)

Got it.
Arduino units with the parallax RFID reader sheild and the wireless network sheild (when it becomes available) telling a central TCPIP listener to update the database when any RFID tags get within range.

...or maybe some sort of pic.

Much cheaper than 4 PCs in every room, and much cheaper on electric too.

i'm by no means technologically minded
but would a portable reader work? [dunno if they can be portable...]
That way you could just wander through the rooms quickly and it'll scream at you when you're close.
Still WAY quicker than having to LOOK through every room.

[also, if you get this working, I fucking WANT one *clicks*]

Yes
You could have one in a laptop I suppose, but it's just not geeky enough ;-)

Can
you attach two readers to one PC and triangulate the location of the tags based on the strength of the signal? That would give you a much better location for the keys. Bear in mind I have no idea how rfid readers work.
