I'd like to thank the development team for this good thing. It saved me a lot of problems (I had a so-called "hardware - router" before, and it didn't work well; portforwarding sucked).
I#m using bitlebee as well... last month I found it while searching for a good IM - Client for my Linuxsystem, and bitlebee was the best choise to make, because I#m already using XChat for nearly two years now.
This way, I don't have to start another resource - eating program (the daemon is little, seems smaller tham centericq for example).
It would be nice if bitlebee would be capable of some icq - features like Visiblelist, Invisiblelist, FIletransfers etc...
