Griffin Technology (booth # 1951) today announced that copies of iFill LE software will be available free to MacWorld Expo attendees. iFill LE streams MP3 files from thousands of free radio stations, from many different genres, directly to an iPod. iFill LE is identical to the full version of iFill, except that LE users are limited to downloading two internet music streams simultaneously (The full version of iFill allows users to download an unlimited number of streams, limited only by the bandwidth of the Internet connection). iFill LE requires Mac OS X 0.3 or later.
