scala (was RE: checksum for distributed debugging?)

I studied scala quite a bit last year.  I was trying to decide which 
language to build my next set of software.  Erlang won out in the end. 
However, I took a strong liking to scala.  I think the language design 
and syntax is fantastic.  I found nothing came close in terms of being 
able to express objects and functions without clutter.  I simply cannot 
praise the cleanliness of scala enough.
   The drawbacks for me were:
	1 - implementation on .net and Java VMs gives you process/threading 
oriented limitations of those VMs.
	2 - few libraries/frameworks that take advantage of the scala.  Just 
wrappering Java libraries will bleed through to your program design.  My 
main reason for going through a thorough language review before starting 
my new projects was I was really tired of Java and the like.

Mostly for these two reasons, I decided I couldn't use scala and went 
with erlang.  Note: this is not a knock against erlang...I haven't 
looked back since making this choice and am quite happy.

So the grand questions is: Can we make scala run on erlang instead of 
Java?  This might be a dream come true!!

thanks, ke han
