 HOWTO Jack - Gentoo Linux Wiki
JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apple's OS X. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves.
JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation.
It is unclear whether this is a bug in JACK, in the new Native PThreads Library (NPTL), or in the 2.6 kernel.

 Open Source Awards 2004: Paul Davis for JACK
The Jack Audio Connection Kit (JACK) provides low latency, high efficiency interprocess audio connectivity, as well as audio device sharing, suitable for pro-audio applications.
So I wrote the whole of the first implementation of JACK and have continued to be the prime contributor to it to this day.
Davis: JACK is unique in that it focuses on two things: one of them is very low-latency operation; secondly, on allowing applications to share audio data with each other.

For other programs who insist on their own audio setup, eg, XMMS or Mplayer, you would need to set their specific options.
So you could tweak latency with "-b", change the jack name with "-n" to relieve identification in an jack control client.
You may get it to work with libaudioss, therefore nearly audio apps that have an OSS output will work with this, and it will be "lag-free".
