I agree, and in terms of implementation complexity it shouldnt be too 
difficult. At least less painfull than dynamically adding and removing 
network interfaces.
BTW: you can issue a ticket in TRACK ( 
https://dev.open-mesh.net/batman/newticket ) so that its not forgotten too 
fast and somebody is using this fancy tool.

Thats interesting but seems too complex for me, can you explain the approach 
in more detail.

From my understanding, Mobile ip means that a node is reachable by a unique 
and not-changing IP address and independent from the current point of 
attachment to an access network. I do not understand how your mobile node can 
maintain TCP scessions with corresponding nodes in the GBI while switching 
the MESH-GBI GW.
