Anyone Deployed Ascend's GRF IP Switch?

SO, the bottom line...has anyone else deployed multiple GRF400's with
Ascend will tell you that UUNET has deployed (or is going to) a
hundred or so.
I want to talk to people USING the technology, not thinking about it.

Your comments and opinions are welcomed.

Yes I have a pile of them, they work well, but there are alot of
gotchas on them. UUNET are using them now btw:

And if you've not used gated before I'd recommend using PC's to do a
mock up of your planned backbone.
