Detailed Description

The base class for Torque's networking protocol.

This implements a sliding window connected message stream over an unreliable transport (UDP). It provides a simple notify protocol to allow subclasses to be aware of what packets were sent succesfully and which failed.

Basically, a window size of 32 is provided, and each packet contains in the header a bitmask, acknowledging the receipt (or failure to receive) of the last 32 packets.
