ebxml virtual appliance

Hi, I just sent off a question to XML-dev asking for wishes for XML virtual
appliances

to-whit "What requirements should one have for an XML virtual appliance
http://www.vmware.com/vmtn/appliances/directory/cat/44

What OS should it run (thinking Ubuntu)
What tools should be configured and set up.
What presets should there be.
What protocols and presets might be useful.

what tools not yet built should there be integrated (these probably prerolled
scripts, for example a script for checking directory of instances against
range of Schema processors etc.)

I figure:

XSV,
Schema Quality Checker,
Sun's multi schema checker
Saxon
Exist

A repository of schemas?
"

Thinking of that repository of schemas made me think, what about an Ebxml
virtual appliance. 

Cheers,
