I cam across a new free service called Chilirec.  It allows your to select and record Internet radio stations for later playback.  Currently there are 300 or so stations although none of the major names appear for example BBC, KCRW and so on.  As a solution it has some exciting potential, and could if it takes off have some interesting affects on podcasting (i.e. you record your favourite programmes for time shifted listening without first having to download or accept any download quality restrictions.

It does however raise all sorts of interesting copyright issues, which probably explains why the major stations are absent from the available list as it would attract the big money lawyers.
