I'm working on a kernel level tunnel driver that would in theory be easy
to hack the features you describe into. I've taken a very generalized
approach to the actual encapsulation so plugging new routines in the
processing path should be just a matter of code.
tunnel0: flags=11<UP,POINTOPOINT> mtu 1480
inet 10.0.5.1 --> 10.0.5.2 netmask 0xfffffffe
transport: (INET) src 10.0.1.60 dst 10.0.1.10
media: IPIP(94) status: ready
supported media: ENCAP(98) IPIP(94) GRE(47) IP_ENCAP(4)
I've not got as far as implementing UDP tunnels or ICMP tunnels :) but
such things are possible as is IPX over IP etc.
