I don't think that has been the case for a while, now.

i think for RFC1323 to be effective, it needs to be working on the sending
and receiving systems, not just the intermediary routers.
RFC1323 can only be supported on TCP endpoints, so there's nothing you can or should do on intermediary routers.

There are good descriptions of general satellite transmission characteristics for IP together with a recipe book of mechanisms which can improve TCP performance in RFC2488. RFC2760 may also be interesting.
