CU-SeeMe Activity Utility (fwd) -- some concerns

Regarding the proposal below, I have the following concerns:

* Some people connected to a reflector may object to having their activity
so widely advertised

* Some reflectors may be subject to non-trivial polling overhead

* Reflectors being used by a "modest" number of participants for "real work"
may be swamped by chanel surfers looking for an "interesting" site.

I'm not deeply opposed to this proposal -- in fact, I suspect I'd use it
during demos when our reflector is "boring" -- but it raises some issues
about the various ways CU-SeeMe is developing:
- One-to-one conferencing
- Private reflectors
- Public reflectors
- ...

> Scans a list of Reflectors and reports CU-SeeMe Activity
> Specifically this program will connect to each reflector, determine

> (no audio or video). After it's gone through the list of reflector
> sites, it displays them on-screen so a user can decide where to
> connect to in CU-SeeMe.
