I think Steve-o mentioned somewhere that there's an interest in pub/ 
sub for market data distribution.

I thought about it a bit and realized there's a very simple approach  
that could meet the dual goals of (a) performance; and (b) exchange  
approval for an internal entitlements system (using an uncontrolled  

This model should work equally well for game data transmission,  
although pub-sub may not be as relevant since the endpoints are not co- 
located (except on college campuses :-) )  However, this could offer  
some advantages as a modified TCP/UDP + P2P re-broadcast model for LAN  
gaming, and could provide localized P2P security.

Key distribution is a standing problem, but is orthogonal to this  

I haven't done enough in the crypto field (pun intended) since the  
mid-80's to be sure that it's right, but I think it's sound, but I've  
been wrong before :-)

My advisor used to say : "In most fields they stand on each others'  
shoulders -- in Computer Science, we step on each others' toes."  The  
goals of doing this is are (a) to reduce toe-stepping; (b) to prevent  
someone from claiming a patent; and (c) to extend the reach of this  
(and other related) platforms.

Is there any interest?  I have been working 90+ hour weeks, but could  
put a sketch together prob. this week, and would like a volunteer or  
two to get us from strawman to woodman or so...
