Hard to say.  It could be tuned a lot more than it is (especially wrt to 
the kernel config).  With a standard Xen kernel I can balloon down to 
12MB and things seem ok.
Ballooning down to 8MB leads to the OOM killer kicking in.

I reckon 16MB is probably a reasonable foot print to shoot for in the 
future.  My goal is to, at some point, build an LVM-aware ramdisk that's 
under 4MB with a full Xen management toolset on it.
