No need to modify the server code.

I think the two questions above are both the same question, which is, "how to I 
get the muscle server to zlib-compress the Messages that it sends back to the 
client=3F".  If I understood wrong, please let me know.

In any case, here is how to tell the muscled server to zlib-compress the 
Messages that it sends to your client:

int32 encodingLevel =3D 9;  // 9 is maximum compression, 1 is minimum, etc.
MessageRef msg =3D GetMessageFromPool(PR=5FCOMMAND=5FSETPARAMETERS);
if ((msg())&&(msg()->AddInt32(PR=5FNAME=5FREPLY=5FENCODING, encodingLevel) 
   // insert your code to send msg to the server here
