Hmmm, if I am following this correctly we are going to need to manually setup a SA for every context we want to send over loopback because racoon can't negotiate with itself? If that's the case I think we really need to get racoon working for loopback because I don't believe the current solution is very
practical ...

I am not fully understanding something... what will labeled ipsec over
loopback be used for?

Someone asked on ipsec-tools list and I could not come up with an
explanation.

To provide the peer label information on loopback connections or
datagrams.  Same as using NetLabel on loopback.

Exactly. getpeercon should work consistently over
 lo
 ethX when two processes on the same machine communicate
 ethX when two processes on different machines communicate

The first two should require no configuration. The latter requires NetLabel, secmark or labeled IPSec and coordinated policy. LSPP.51 was almost there and is what we are still using internally for applications development.
