Maybe it's a solved problem and SOAP 1.2 is good enough for that particular job.

We _still_ use TCP/IP and it's v4 is from 1981.

edit: I once looked deep into Remote PowerShell. How it's actually built. Dear. God. XML enveloped inside XML inside another XML wrapped around HTTP. Add some certificate based encryption for the HTTP envelope and some more encryption for the Kerberos messaging inside the serialized XML wrapped in envelopes and wrappings. Now THAT'S a communication protocol. :D
