if I understand the document correctly each mesh node a client connects to 
will send a roaming advertisement back to the last known mesh node this client 
was connected to. A few questions come to my mind:

 * Does this already work with the current code ? If not what happens now ?
 * How do all nodes get back in sync ? It sounds to me like for certain while 
a number of nodes claim the same client, right ? Nobody tells the intermediate 
mesh nodes that their client has moved.
 * What if receiving a roaming advertisement triggered an immediate 
(unscheduled) OGM broadcast ? That would potentially speed up the gap and also 
address the "longer path" problem you outlined in the wikipage.

Regards,
Marek
