its CAV already full stable/compatible in server platforms?

I wanted to know if at this stage CAV can be run in windows 2003/2008 any edition?

Although I haven’t seen mention of it, the CESM beta may support these. But previously CIS/CAV has not officially supported these OS’s.

I have it running on several 2003/2008(R2) 32/64 bit versions.
In general it runs fine as CAV, I have had some issues with running FW & D+ on some servers but not on all, it seems to depend on the roles/applications/tasks the servers are running.
