My sum up would be

JVM :
 Official version closed source and therefore unavailable
 open source versions available but not certified/approved
 Not designed from the ground up for JITs
 VMs tend to be slower and more resource hungry - would need high  
quality JITs on multiple platforms to compete with mono. (How good is
Kaffe in this respect?)
 Designed for Java language - not as suitable for other languages
 Might need a lot more work to develop open source versions up to same 
standard as Mono (JITs mainly) - years away? 
	


Mono :	
 Technically superior to JVM
 Designed/optomised for JITs
 EMCA core is royalty free - no threat from patents
 Royalty free is obviously GPL/LGPL compatible
 Already functional and almost complete - should be ready for Gnome 3
 Supports multiple languages - Java and Python languages currently under
development


My Verdict : Mono give you everything JVM has plus lots lots more - it
even supports the Java language. A high performance open source JVM +
JITs is a long way off unless companies are willing to donate them of
course (SUN, IBM et al) and thats the only realistic way that it could
be considered.
