I think this is the solution to a different problem. If
your Windows boxes work OK for a while and then gradually
"drop out" of the pool, then it can be due to lost UDP 
packets in certain network situations. The above is one
solution.

This sounds like it may be a firewall problem. Being able to "ping"
whilst a good
start isn't sufficient. Do you have the appropriate udp and tcp ports
open in both
directions between
* first of all: the central node (neg+coll) and all other nodes?
* secondly: all potential submit with all potential execute nodes (and
vice versa)

If not that, it could be something to do with the names. Maybe turn on
some debugging
(in the Collector for instance) and try connect a single linux and see
if anything gets through.
