What do you mean by protocol "Microsoft compression for PPP"?
But back to the compression thread some time ago here - the only two
compression protocols implemented in Cisco routers, the vast majority
of terminal at ISPs, are:
1) Stac-LZS [RFC 1974]
2) Predictor compression [RFC 1978]
Stac-LZS is also implemented in M$ W*s but unfortunately (as I have been
told by some kind soul from the list) the algorithm's license doesn't comply
with GPL (GNU General Public License) and probably with OpenSource generally.
But Predictor can surely be implemented, can't it? I know that it can't
achieve superior compression ratios but better this than nothing. Isn't someone
already working on it? There are even C-language examples in the RFC and
the compression/decompression isn't much complex so it would be easily doable
(with help of bsd_comp/deflate skeleton), I think.

I don't know any compression-related changes in 2.3.5-2.3.7 but the upgrade
is worth it anyway.
