Do not do broadcasts. With broadcasts you increase the load of all
machines on your local ethernet. For that reason multicasting is invented.
It is quite easy, if you have a unix-box as server, especially on suns.

For software have a look at
http://www.merit.edu/~mbone/index/titles.html or 

Another possibility is, that you configure your box as http server and
then have on one page with a videostream (using e.g. 
http://www-vs.informatik.uni-ulm.de/soft/wv/ ). The advantage is that
people whio like to see it do not need any specialized software. Netscape
is enough. 

Third possibility is using cuseeme. Abot that I do not know very much.
