Well, following Tzafrir's lead, I've just installed a 1.6.1-rc1 on my 
vpslink server with a res_timing_pthread time source, and the sound is 
slightly less clear but had no choppy sounds in the 5 minutes I played 
with it.

I assume this has more to do with the time source than the 1.6 upgrade, 
but I don't know that.

It's possible that a ztdummy driver on openvz provides a good enough 
time source that makes it work better than Xen+pthread -- if that's the 
case, lylix.net would be superior. A friend of mine is trying them now, 
we'll see how that works.

As far as vpslink is concerned, I've been unsuccessful in getting a 
ztdummy to work. It's a Xen setup, but you can only use a very specific 
centos kernel, no matter what system you are running -- just getting the 
ztdummy to compile with the required gcc-4.1 for that kernel is a lot of 
effort. And when the module didn't work, I gave up.

Tzafrir, do you know of any OpenVZ provider that charges something 
comparable to the $8/month vpslink plan?
