Here is how I do it.  The LWIP code runs as it's own task.  Messages that 
are to be sent out over TCP/IP are placed into a FIFO type of buffer.  
Each time the LWIP task runs it tests this buffer to see if there is 
anything to transmit, and if so calls the appropriate routines.  When 
TCP/IP packets are received, the process is reversed, the received data is 
placed into a FIFO buffer by the receive callback.

All the source code for this is published on the OpenEZ web site.
