Sounds like "Network-of-Clusters" to me? (in the tradition of NoW etc).

I may have misunderstood you here (?), but reliable net-os's are 
definitely a "solved" problem, although the performance overhead is 
sufficiently high that they aren't always practical.

If you think about it, the international banking system would be in a 
lot of trouble without reliable net-os :).

To people not accustomed to Dist-Sys it is more "natural", probably 
because it's an example of the classic "divide and conquer" approach to 
an unfamiliar field. It's just unfortunate that in reality it sucks for 
Dist-Sys :(.

Twisted is neat (having watched for it for a while now), although I've 
always tended to think of it as "a simplified JBoss" - sort of like 
BASIC compared to C++; smaller, leaner, easier to use. If I were a 
Python programmer, I'm sure I'd use Twisted rather a lot...
