Ah well that is another story isn't it? 

You can do two main things to share knowledge between processes in
Erlang:

	1) store it in ETS

	2) store it in the State data of a server process

The latter is probably a more pure solution.  You can call ETS
cheating in the same way that the process dictionary is cheating
if you wish.  I call it optimizing. :)

I use ETS quite often for this purpose.  I'm especially prone to:

	ets:update_counter(Tid, callReference, 1).
