Indeed, (Had lots of beer tonight)
We would all like a go at that!, but sadly we are never given a profile that allows people to find us without really delving deep into the listings, most stations are getting nothing but 'by chance' hits, pushed down by cheats and so a look at the logs reveals low listen times. Many servers, for one reason or another, never actually hit the .yp directory . I bet many other streams are of good quality, but we are stuck in catch 22 where you are not visible enough to get people to try them out.
No, I won't really tell, coz it would wreck .yp even more.
And no, you don't need lot of I.P's (Ref - 127.0.0.1, F-spike, Shoutcast 1.6B or earlier) if you understand that, then you understand what a TCP dump would tell you on the offenders 'encoder' network.
