AFAIK, no one has done this. The dhcp-over-ipsec was only implemented
by Microsoft and SSH, and they were not compatible with each other.
Openswan-2.3.0 has XAUTH and ModeConfig support though, which should
be able to offer you the same functionality. But it's very new and
likely not complete yet.

Ofcourse, IKEv2 should make all of this stuff obsolete too, but that's
not going to happen anytime soon.

I guess with some creative _updown scripting, it should be possible.
