20,000 network connections per tcp server + max nodes

[Joel Reymont]

I know we have been discussing this before but... Someone just asked  
me a question of how much hardware would be required for my poker  
cluster to support 500k simultaneous players.

My understanding is that Erlang would max out with approximately 250  
nodes. This means that I need to support 20k players per node and I  
really don't think that's possible.

Any suggestions?

     Thanks, Joel
