Its a funny old world this game of computers.... I could say the same about planes lol but computers are my game hehe I just read these forums out of interest...
Enough of that what you are after is netcasting not broadcasting.
Here is a link about specifying your netcast server from powerpoint

although if you search on google for powerpoint and netcast you will find more pertinent results on what you are looking for.
Hope this helps - feel free to PM me if you want/need more detail.
Cheers
