Re[2]: Multicasting ion about cu-seeme

Do all flavors of UNIX have the multicast capability?
Your answer seems to imply only certain ones. If no, which
flavors or vendors have this capability vs. those that don't?
I.E. SUNOS 4.1.x

Thanks in advance. :)

The reflector, since it runs on a UNIX platform, is able to take advantage of
the one to many functionality of MULTICASTING on those UNIX platforms that
have MULTICAST capability. Unfortunately, the PC's and MAC's don't yet have
this capability in ther TCP/IP stacks, so the reflector can only use
MULTICASTING with NV and VAT, and to connect to other reflectors.

As MULTICASTING becomes available on PC and MAC platforms, rest assured that
we will have versions of CU-SeeME that will take advantage of it.
