First of all, there are two distinct questions:

1) Whether allowing SVC management to be directly controlled by applications,
   and specifically by the QoS and/or traffic requirements of the applications
   is a good idea or not

2) Whether allowing SVC management to be directly controlled by applications
   and specifically by the QoS and/or traffic requirements of the applications
   runs counter to rsvp and int-serv directions

So, I would suggest we'll debate these two questions separately.

Wrt to the first question, I've yet to see any compelling technical
argument that would show why placing SVC management ("local/remote",
"dedicated/shared") under the control of QoS is a bad idea.

Yakov.
