Well, I'm willing to comment on just about anything, I suppose...

CompuServe's V.32 nodes have MNP5 and V.42bis compression.  
Supposedly, it will actually connect with these.  However, it is 
useless, because the port speed is locked at 9600, to avoid flooding 
the backbone network.  So, it really doesn't help to use the 
compression -- yet.  CompuServe _is_ planning to upgrade their 
backbone links (9600s become 56/64kbps, 56k become T1, T1 become T3, 
etc.).  When that is done, they plan to increase the port speeds to 
at least 19200, maybe 38400.  To avoid the need to replace the 
modems then, they went ahead and bought modems with compression NOW. 
They can reconfigure the modems remotely across the packet network, 
so when the time comes, all they need to do is enter a few commands.
