Maybe it would be worth doing, and simply accepting the fact that if you have
a situation where your packet size is no longer sufficient to handle the
number of SA's between your two gateways, then you need to look at other
transport media. So if you run out, you'll have to look at a TCP/IP
implementation of IKE instead of UDP.
