There may not be as much Icecast stuff but internet radio is doing very well. Someone else has already mentioned nts.live (it has a huge range of stuff, more like a radio station) but other UK-based stations are balamii.com, supremefm.com and rinse.fm (Rinse used to be a pirate radio station but went legal).
