I have been porting out the multi-player aspects of Perenthia into a separate library I hope to get up on CodePlex before too long. What the library will provide is some interfaces and classes related to handling multi-player environments. A central static class will manage connected clients and three protocol classes for HTTP, Polling Duplex and Sockets will use the static class to retrieve connected clients and push information down to them. A simple set of "tags" are used to send information back and forth and some providers allow for defining your own implementation of handling commands and encrypting data.
The library will be focused on providing an easy way to get setup and implement a multi-player structure. You will still need our own game engine and associated components.
As soon as I get it cleaned up a little and tested out I will put it up on CodePlex and provide a tutorial and sample application showing how to implement and use the component.
