What functionality does PVC give you that the ethernet VLAN does not?

Shaping, for one.

There is nothing inherent in Ethernet which precludes shaping.  Low- and
mid-range routers can do it just fine.  If your core router doesn't, speak with
your vendor.  Then again, do your core routers really support shaping on OC192
FR either?

What is the current max speed of frame relay in any common vendor
implementation (I'm talking routers here).

Doesn't OC48 POS on GSR and Jewniper do FR?

If those boxes approached the reliability of carrier FR/ATM gear, that might be
relevant.
