[asynchrony]

Anyone have any experience with messaging frameworks we could use to
replace JGroups in our application? So far we're under the impression
that JMS would be overkill and we're concerned about discovery times
with JXTA, but its not quite out of the discussion. Right now we're
still considering hub & spoke options, but we'd like the flexibility
to go to p2p in the future. We'd really appreciate any input.

Thanks,
Tim

P.S. JGroup Issues we had:
JGroups would remove a node [it would go out of wireless range] and
when it re-entered the network, the network would become split-brained
and there would be 3 groups of nodes being combined instead of just 2
[the node that left and the group that contains everybody else]. Some
nodes would be pulled from the original group and join the group the
re-entering node created.We then had trouble getting them all to come
back into the same group.
