If you don't negotiate proxy ids but your ENCAPSULATION_MODE attribute 
specifies tunnel mode then I guess you can stuff anything in that tunnel.
Lots of people may consider it a local policy decision on whether to accept
anything out of the tunnel though.

You could negotiate a proxy id's type of IP_ADDR_SUBNET with the addr 
0.0.0.0 and the mask 255.255.255.255 and have port and protocol both zero and
probably achieve what you're looking for. In that case if someone accepted
it they'd be acknowledging that anything can come down the pipe.
