Hmm. How are you measuring latency? I'm not sure how to do it (sufficiently 
accurately). I'm running SuSE 8.2, which some have suggested includes the 
low-latency patch, but I don't think so. I've been too busy (lazy?) to check 
or implement. I find even when playing some .ogg file to jam along with, that 
hiccups are "disturbing" or distracting. Maybe I've got problems (as a 
musician wannabe) with my timing? I've got my .ogg files on a server, but I 
believe xmms pre-buffers (I recall setting it to 1/2 second at one point?) 
its compressed audio stream, so I think I'm only hearing jitter from variable 
interrupt response (and temporarily blocked interrupts?)?

Your other comment (in another post) about "real life lost packets" (UDP 
comparison) is interesting. You would have to transmit a time code in each 
packet, so the player can continually "re-sync" the audio. I don't think the 
current audio streams do that? I think they "assume" (Benny Hill?) that the 
audio stream is continuous, and therefore you can derive the timing?
