I'm not sure if this has been said already :

At OLS, we had a talk with denis, pavel, eric, daniel, benjamin and others,
and we agreed to cooperate on eric's netns patchset which seems to satisfy 
most of the stake holders :
	* openvz
	* ibm
	* eric (hopefully :)
	* planetlab (heavy users of linux-vserver) 
	* hp (also interested)
	* google (?) 

the planetlab team successfully included eric's netns patchset in the 
linux-vserver patch and had good results with it.

the following tasks were discussed : 

	* improve the patchset to make it acceptable by the netdev community
	* share a netns git tree 
	* share some tests framework all parties have been developing 

Are we in sync ? I'm sure there are more interesting stuff to be said :)  

We're looking for a place to host the netns git tree while we are working on 
it, which means we will need first a federator for the pachset. Eric declined
as he is too busy. Any proposals ?
