I have thinking about it and mine decision is that JVM never get
strong isolation, reliability and soft-real-time characteristics as
Erlang have but Erlang VMs can improve their performance. I think that
HiPE is great but it is little bit pushed to its limits. Great things
happen to dynamic languages compiling this year and especially Trace
Trees comes on mine mind. Applicate Trace Trees approach to Erlang
should be next big thing. Unfortunately I'm not experienced enough to
try prove it and doesn't heard of anybody else who even start thinking
about it.

P.S.: Sorry if you have got this message twice, I have some issues
with using multiple gmail accounts and this mail conference. One of
them must have changed something :-(
