 * rpctrans.h - buffer I/O to transport
 *
 * Description:
 *
 *	This is just a layer on NetBuffer, which provides for buffering
 *	of a raw NetTransport connection.  RpcTransport just does 
 *	encapsulation of sized data blocks, ensuring that the exact 
 *	buffer sent is recreated in the receiver.
