If you have a home you should be able to add your stream to that property and invite guest over for a party, this is a great way to test things out with your stream and having a live event, but be careful you get a good stream that Linden likes cause the Linden homes tend to have issues with people doing this the inexpensive way. They want you spending money to be a DJ apparently so i used my dedicated server that i already own for business to setup my own relay with icecast so not to pay SL or it's sponsors more then they deserve, when prices for owning land come down me and many others i know will be spending much more real money in this grid
