Mike at irclone.com let me know via e-mail that they have no plans to support the URC series. I was hoping since the URC-200/300 appears to have more features than the MX-500, and are targetted toward consumers, there might be more potential customers. I guess time will tell. After looking at the 500e software demo, I can see that it is coded specifically for the MX-500 feature-set, and would probably be a lot of work to update it to work with the URC remotes.
