RealNetworks Targets iPod
RealNetworks has debuted its Harmony software, which lets users play digital music on virtually any secure device -- including Apple's popular iPod. Copyright and patent issues also may be brought to the fore if Apple decides to get tough with RealNetworks' competing technology.

Some of the other articles I've read about this (including one in the Wall Street Journal today) argue that Apple could sue under the DMCA, which was passed to prevent the circumnavigation of copy protection devices. I think Apple would have a tough argument to make here. Real Media's software does not open up iTunes downloads so thay can be copied anywhere (like Hymn does), but rather adds their own downloaded files to the iPod, using the DRM solution already in place. Real Media isn't breaking the copy protection per se, but integrating with it.
At any rate, for so very long I have hated the way Real Player takes over your desktop and annoys the crap out of you, it'll be a long time before I'd install another piece of software from Real Media.
