So I've got my IPSec network tunnels up and running nicely, using 
ESP/Transport. Now I'm interested in adding compression to the mix. Any 
ideas? None of the stuff I can find on the web seems to talk much about 
compression, only that it's supposed to be an integral offering to IPSec.

Pointers would be much appreciated. Requests for further info will be 
answered promptly. Please CC replies, as I am off-list. Thanks!
