I'll put a vote in here for the sACN Gateway boards made by Jim St. John at SANDevices (http://www.sandevices.com). The E682, in particular, is a really flexible board and a very inexpensive way to get into the kind of DMX-to-IC chip translation that's necessary to drive pixel strips that use chips like the WS2801, HL1806, LPD8806, TLC3001, and a bunch of others.
The E682 board can drive 16 sets of strips, and while not every strand is completely independent of the others (the board is divided into four clusters), within each cluster you still have a lot of flexibility. Currently each E682 board can address 6 universes of DMX, but there's some potential for future expansion. Pixels also can be grouped, such that a single set of RGB DMX addresses can control two or more pixels in a strand.
If you don't need hyper-resolution in your application (in my case, I'm doing a lot of cove lighting, so the need to have individual, point-control of each pixel is not always there), you can control an obscene number of pixels with this one board.
I don't work for Jim but I own five of the E682 boards and am really intrigued by the possibilities these boards present. The board is available pre-assembled or as a kit, and I'll vouch for the fact that it's also a fun electronics project to build for those with somewhat above average soldering skills.
Cheers,
Matt
