The articles are at http://thinkerlang.com and I plan to add to the  
collection now that I'm scaling RabbitMQ, ejabberd, etc. on Amazon EC2.

Tying the new EC2 load-balancing, scaling and monitoring services into  
Erlang should work particularly well!

The intractable (I think) problem is using Mnesia as a backend for  
internet services. I don't think it can be used since there's now way  
to automatically sync up the various database instances after a  
network split.

Imagine customers transacting with two separate Mnesia db instances  
without without replication happening between them. Horrors and  
balances gone awry!
