CentOS virt - May 2010 - SPICE anyone?

There was mention of some support for SPICE in RHEL 5.4, and mention again
of improved support in 5.5, but it sounds like their main goal is to
implement it in RHEV.

Is there an easy way to implement SPICE with 5.5? Or should I download the
source and compile it from spice-space.org?

Thanks...
