addressing a lot of processes

[Chandrashekhar Mullaparthi]

That is right. atoms are not garbage collected. For the number of 
processes you are talking about, you really don't need to worry about 
performance. The lookup table from IP->PID should perform well enough.

The basic rule of programming in erlang is not to worry about 
performance first, but to implement a solution to your problem in the 
most intuitive way. Then you test it and only then think about 
rewriting if your performance requirements are not met.
