Of course, *any* tunneling scheme is going to have overhead, compared to native multicast routing, but maybe you've decided that the overhead induced by "mrouted" is not worth it. (However, I've been using it over a 33.6 modem for more than a year now; sometimes I *do* notice the effect of route exchanges, but mostly not.) >UTG also >works on Win95/98, since the client is Java.

This does multikit<->unicast<->multicast tunneling, rather than just multicast<->unicast, so you can use your existing multicast applications (except for the session directory) as is. (OTOH, one potential drawback compared to UTG, is that it doesn't do any actual 'transcoding' to lower bitrates - instead it copies the UDP data 'as is'.) There are pre-built versions of multikit/liveGate for Windows, FreeBSD, Linux, Solaris and Irix. Ross.
