It is doubtful. Steamcast and icecast are able to allow more frequent updates due to the much lower size of their respective db's. If either icecast or steamcast saw 6000 servers at once they would respectively increase their touch times.
Just do the math 6000 server's all touching at a frequency of 1 minute that is 6000 hits per minute and each one of those hits equates to no revenue. Expanding this out 6000 * 60 = 360,000 hits per hour * 24 = 8,640,000 per day (more then most sites see in a month) * 30 = 259,200,000 hits per month, each touch message accounts for approx 500 bytes of data 129,600,000,000 Bytes per month. I dunno know about you but that is alot of traffic and alot of transit data.
What needs to happen is a redesign of the yp mechnism to offload this onto users and individual servers.
