Google's Desktop Search 1.0 has been recently released and there are already a couple of plugins for it, but is it possible to search password encrypted chatlogs, using a plugin wherein you enter your password?
There are already plugins for trillian and mIRC, and this should be a very handy feature, this will make it a lot easier to search in your chatlogs (If i am looking for something, and you don't know in which month you said it or tho who you said it, you have to go through alot of files, for example)
