Well about March of 2010 I found Erlang and I checked the University
library here and they had this book and I checked it out.  I ordered a
copy from amazon and hope to get a few signatures next week at the SF
Factory :)  It's old, but the basics probably still hold.  There might
be a general issue with debugging spawns/receives, etc.  Hopefully
I'll have more input by tomorrow from some folks over the sea :)

I think I've been there a few times.

Ordered it a couple of weeks ago and got it last week :)

I've seen these on the erlang.org side panel and might look in to them too.

thx for the tips.
