I understand that that might come in handy at some point. I haven't had such a situation though. And you always have the note field to store extra info.

The problem is that i don't want to enter passwords twice. Once on my N900 (or PC) should be enough. And then an rsync command (or similar) to update the other version.

I tried compiling keepassx for N900 but it doesn't work well. I can read/edit the database but the interface ***** on the N900. Your interface looks nice and clean.
