Likewise, clients for Android and OS X are needed.
Those are being worked on, according to the Nomad page.
I have noticed a couple of issues with the iPhone client (running on an iPad 1 with iOS 4.3.5):
I have 3 DVRs and a long playlist (over 100 titles). One DVR in particular has a very long list. To make scrolling easier, I sometimes "hide" that DVR. When I do, it's playlist sometimes is hidden, sometimes not. When it is not, trying to select a program on the "hidden" DVR instantly updates the playlist correctly.
When I try to "enable" a hidden DVR, it's playlist is usually not added to the Nomad app unless I exit the app and restart it.
This is after waiting for the "loading" to complete.
