Great to hear.

Are you using it for real-time Multicast, e.g., IPTv, or 
non-critical Multicast?

Our target is to use mLDP for non-critical, data Multicast 
services, and leave RSVP for IPTv and such.

Is Graceful Restart supported, at least?

Well, LDP has no link-protection capabilities, so not sure 
how those would come to mLDP.

What I know Cisco are doing with their mLDP implementation 
for now is link-protection, but via RSVP. I haven't tested 
it, though.

We're still relying on Graceful Restart for that.

As one would with any pre-R4 release :-).

Yes, we're certainly interested in having those features 
there.
