I ran across some SMD RGB Flex Strips on Ebay that look pretty interesting. Its sold by the meter and comes with an IR remote/controller. The controller is useless for our purposes. They sell them in two versions: 30 and 60 LEDs per meter.
The seller also lists their contact information and is open to bulk purchases if anyone is interested in a coop. You can see the 30 LED here and the 60 LED here. The pictures seem to be the same so not totally representative. They look like the 60/M version to me. They can be cut every 3 LEDs but probably would have to be resealed. I haven't purchased any yet so I can't speak to the quality.
