Hey everyone, I'm sure most of you are familiar with the program X-Fire and it's useful in-game messaging feature. I was curious if anyone knew how this works, how it is able to run without stopping the game at all. I would be interested in developing an in-game messenger which uses aim, msn, yahoo, etc. instead of just the x-fire network. Maybe I'm a dolt and there already is a program that has done this, if so that'd be awesome but I am still interested in this technique. Anyone know anything?

Anyone have any clue?
