With more people moving to google+, I thought I'd write up how to link Facebook chat (and MSN) to Google Talk. This allows you to chat to people online on Facebook without actually being logged in.
This write up uses the Spectrum.im transport, hosted on one of my servers. Its all experimental, and I do have a habit of breaking it on the odd occasion. What I'm trying to say is, I offer no support for this at all, and it isn't my fault if your phone explodes or the earths magnetic field reverses. :)
