Ive moved the content of this page to AlternativeCommunications, to fit the page-naming guidelines of the wiki. I did a bit of restructuring as well, hopefully clarifying the tips on this page.

meh.. can you delete the trick bout stream url's because i missed an important point which is to get the stream url

It's just an example of alternative communications which could be possible in some way.

llSetParcelMusicURL is a perfectly valid form of alternative communications :-)
Though, instead of allowing us to communicate from object to object, it only lets us communicate from object to external server - which is very useful.
Check out its entry on the AlternativeCommunications page.
