Any idea when this might happen, and do you need any help?  I definitely
need these changes, so anything I can do to expedite that will be done.

I added a handler to check for RR reports, but unfortunately my server does
not send them.  I verified this on their forums as well (we're not using
Darwin, but the general idea is the same).

So, I guess my only option is to modify the library to do a per-RTPInterface
variable that tracks TCP failure.  Would you have any interest in this
change if I supplied a patch?

Thanks for your help.
