Sometimes my 128K ISDN link gets utterly swamped by big route updates... It's amazing that you find it useable at such a low bitrate. Maybe you know some configuration tricks that I don't? I'd really like to get a look at your mrouted.conf and the one on your host :-) > >UTG also > >works on Win95/98, since the client is Java.

Thanks for the pointer... This looks _very_ interesting. I'd still like to get UTG up and running just for the heck of it, though :-) > There are pre-built versions of multikit/liveGate for Windows, FreeBSD, > Linux, Solaris and Irix.
