In fact, inside the EuQoS project, we intend to manage several 
technology (in particular the access part) across a common view of the 
QoS. This why, in our architecture there is 2 view of the Control Plane. 
One which technology independent and manage the inter-domain and the 
other which is technology dependent and manage the intra domain part. 
So, from the DiffServ point of view, this could result to setup 
approriate L2 mechanism in order to provide a DiffServ aware QoS 
mechanism. For example, in xDSL ATM or GE network, the EF class could be 
map to a CBR ATM ATC or a particular VLAN. This could be also apply if 
you intend to used MPLS-DiffServ mechanism.

I get answer from FT people. So, normaly someones from FTR&D will attend 
the BoF attempt. From EuQoS, I'm not sure someone could be present.
