massive tcp servers

[Dustin Sallings]

	Does anyone have any experience with massively large tcp servers?  I'm 
doing something like a chat server where there will be many, many 
connections simultaneously along with some mechanism for addressing 
those connections.  Does anyone have any idea what might be required to 
have something on the order of 10,000,000 concurrent connections in a 
cluster.  Obviously I want as small of a cluster as possible for 
hardware costs.  I also get the impression that large clusters may not 
be that easy to scale.
