Sri - I agree that specifications allow certain handovers.

I am not sure what do you mean by Mobile VPN?  Mobile IP using a MH-HA 
tunnel with a VPN-style tunnel?  A VPN which changes the source address 
with a new IKE exchange?  These are two different things.

In my experience, once I successfully set up a VPN tunnel on a Host 
computer its Mobile IP implementation will no longer work, and 
vice-versa; although each one can support mobility ok, independently, to 
a certain extent.
