Noone uses udpcast? Its such a great tool.

Im sure it wouldnt be too hard to make a patch. Ive changed our imagingserver to NetBSD 3.0 from Linux and desperately need to get it working.Im not aware of any other open source utility that can multicast.

It seems that udpcast cannot bind to rtk0. I will try a different NIC, but
Id still like to get it to work.

Any help appreciated.
