Actually I verified the fragmentation support from Finland, and they
said it was requested, but it is not in any product yet, and as Paul
Wouters already commented to list that the problem with some
implementations sending fragmentation regardless whether it was
negotiated or not has already been fixed, I requirement to implement
this quickly has gone...

Anyways, if there is already more implementations doing IKE
framentation, it might be good idea to think whether we should
standardize that. On the other hand I am not sure if they are well
enough documented so that different implementations actually talk each
other...

Anyways we should most likely act fastly if we want to get this fixed
for IKEv2.
