It doesn't use SCM_RIGHTS yet (more precisely, I think I'm the only one running that extention), it won't be using RFC1149 (look it up) until 20.6, we have no plans to pass session snapshots down a pair of tin cans with string, and won't be adding embedded Perl/Awk/TECO support with automatic language sensing until at least version 21. Other than that, I think it uses just about everything... including the kitchen sink for some versions... (try Win32-based GNU Emacs, or XEmacs.)
