I too have been waiting for a universal remote for Android for some time. A while back there was a Harmony One app available on the market, but all it controlled was Google TV.
Logitech has a remote in the market for SqueezeBox, but nothing to control your TV, Cable box and all of that good stuff.
I do have Unified Remote that controls my computer, that's pretty cool. But the day they come out with a remote just like a Harmony One will be the shiznit!
Only thing is, they probably aren't in any hurry to bring that out since they sell the Harmony One for like $100 bucks and they know nobody will want to pay anywhere close to that on the Android market.
