 From my notes of that meeting with the AD I have:

There were the following drafts that are still WG documents at this  
stage:

- the outstanding applicability draft (draft-ietf-shim6- 
applicability-03.txt)

- the locator pair selection draft (draft-ietf-shim6-locator-pair- 
selection-04.txt)

- the API draft (draft-ietf-shim6-multihome-shim-api-07.txt)

There may be work on Illitsch's proposal to perform a faster algorithm  
in the failure detection / reachability area (he had a draft on this I  
recall)

There were areas about ULP / SHIM signalling to allow greater levels  
of control in an instance of a ULP and greater levels of feedback from  
the SHIM layer.

There appears to be interest in multipath TCP, andf the possible  
coupling of multipath TCP to Shim6

There was interest in proxy shim6 and a draft on the topic (draft- 
nordmark-shim6-esd-01.txt)

I must point out that the past two years has been spent largely  
waiting for the documents to clear the IESG, and the lack of work in  
this WG in the interim was due to a decision to await these core  
documents to be cleared through the IESG before picking up more work.

So if there is interst in picking up this work now, it would be good  
to hear from intersted individuals in response to Jari's call.


thanks,
