well, firefly running with mDNS AND avahi at the same time conflicts.
You should build firefly around avahi. At least thats what Ron suggested somewhen. iirc.
Well, whats a NDS?
I run firefly on my NSLU2, and i can share niceley through banshee or rhythmbox through avahi on my PC. Its all wireless, and all works fine here, also latest avahi patches and stuff.
But maybe its the combination of mDNS and avahi…. *shrug*
