The SEAMOBY group is also looking at Candidate Access Router discovery for seamless handoff. They will need to handle VPN's and possible handoff between disparate address spaces at some point as well.
The tunneling/routing header discussions may be common in some cases, too.
The needs of IPSRA and MIP with respect to longer term enhancements to IPSEC may also be similar.
Separation of encryption equipment from the endpoints themselves is not speficied in MIPv6 right now but will certainly have architecural ramifications away from the current end to end model. It might be best synergized as part of local mobility management which allows for such a point to point or subnet to subnet gateway models.
If I were you I would focus on the local mobility management aspects of the WG to find some initial synergy.
Hope this helps,
Glenn
