The claims sound somewhat like SP4, with the obvious extension
to the TCP/IP 5ish-layer world rather than the OSI 7ish-layer one
(using sockets to reach application layer rather than
session/presentation/appl.)
SP3 was the above-layer-3 protocol, and I think SP4 was above-layer-4
rather than bottom-of-layer-4, but it's been a while.
