I appreciate Stan's predicament.  He's trying to port a
trusted multilevel distributed database to several multilevel
platforms, and their interfaces share no resemblance.
POSIX .6 doesn't begin to address interfaces to multilevel
network protocols.  If POSIX .6 were adopted and universally
implemented tomorrow, Stan would still have to deal with
syntactic and semantic differences between one company's
lrecvmsg(), another's recvlmsg(), and a third's recvmsgl().

Still, I agree with Gary.  TSIG has enough excitement
resolving technical and territorial issues with IETF.
Trying to also become the fast-path alternative to POSIX
will spread TSIG much too thin.

Most of the vendors who participate in TSIG also send
delegates to .6.  Perhaps one of those representatives
should start a trusted network API discussion.
