Purchased Poke Eye
($1.99 at the iTunes App Store) and extensively tested it.
It works. Indeed it is very responsive and well designed. For anyone in my boat (no native Apple Remote support), it is the best option for EyeTV control. In the future, with improvements, it can become the must have EyeTV remote for all users. I recommend it.
However it *is* in dire need of improvement:1) It needs stay connected/keep device awake options
a la Rowmote. This is by far the biggest issue -- if you are watching a commercial laden recording, you want to be able to skip through commercials immediately, not after you have unlocked your iPhone and reconnected Poke Eye. Yes, this can vampirize the battery, which is why it should be optional, but it is essential. As it will tend to be used at home, with a charger readily available, most people will gladly sacrifice the battery for performance.
2) Stability -- it did crash once during reconnection.
3) Episode names (please do keep the dates as well) for the recordings. One thing that would be great is an option to keep them ordered alphabetically by show, the way they are now, but oldest to newest by date within each show.
4) Support for EyeTVs full screen menus. You'd need a Menu Key, Up/Down arrows, Select.
5) FF/Rew keys.
6) (And this is strictly in the extra credit, v 2.0 territory) Ability to control the onscreen progress cursor, the way you could with a mouse, so you can find a specific place in a long recording. Telling us what's playing, a la the Apple Remote for iTunes.
7) (Again extra credit) Add Front Row/Apple DVD player support to make this the one stop Mac HTPC remote.
