working fairly well here. there are some bugs but not what I would call showstoppers. Here is my hardware
AMD athlon dual core 3800 with 2GB ram
Separate HD for BFD (400GB)
Emu1820M PCI audio interface
WinXP Professional SP2
with this config, I can run BFD standalone at about 2ms latency, which is not noticable to me.
