Welcome to Erlang! :-)

I believe Erlang is really a good choice for you. You list all the right
words, fault tolerant and distributed to mention two.

Ulf Wiger, chief architect of the Ericsson success ATM-switch AXD301
pointed out an article in the Ericsson internal newpaper "Contact" some
time a go here on the mailing list. You will find an english version
following this link:

AXD301 is part of the ENGINE concept and has a control processor programmed in
Erlang. Something like 1.5 million lines of Erlang code (Ulf, correct me if I'm
wrong).

There are many people working for Ericsson, no longer working for Ericsson
and even working for Nortel who can testify to that they have acomplished
a lot of "good things" with extremely high quality on time with Erlang.
Including my self.

You can purchase a commercial license from Ericsson. There are also a few,
including
my own, consultancy companies who has Erlang experts.
