Yes, you can use LEDs which support 1 wire and a fixed clock like WS2812s, just need to switch up your pixel.rc file to match...I've actually just made a much larger display with WS2812s which is around 5,000 pixels.Remember - you don't need power to be managed through the pixelpusher to use it. If you think you're going to draw more than 25A, just shunt power straight to the LEDs and have the PP manage data only. You'll have to share ground between them, but that is all.
For wattage of power supply, take current per LED and multiply it by the number of LEDs. You can under-rate this a little bit to save some cash if you know you won't blast them all to white at the same time. (i.e. 60mA * 4000px = 240,000mA = 240A @ 5V. 240V * 5V = 1200W power supply req'd).Adafruit has a really good primer on this and how to distribute power amongst the LEDs here: https://learn.adafruit.com/12mm-led-pixels/powerHope that helps!
Hi! Ws2811s and 12s have a fixed clock, so there is no clock wire. I don't know if the 12b's are officially supported by pixel pusher or not, but you can run the 2811s by setting that for your strip parameter in your setup file, and you can use onewire as a multiplier to match the clock on those LESs.

I'm on Arduino 1.6.11 using a Due over the programming port. Thanks!
Hi - I'm getting all kinds of errors trying to get this compiled. Any input? 'cli' was not declared in this scope'PIND' was not declared in this scope'sei' was not declared in this scope
That's a really weird one. Are you setting the strip attributes correctly in your pixel.rc file? See step 3. You could also try using swap to swap the data and clock lines in your setup...that could be it...
It has to do with mapping. If I used 9x outputs, I could make each of the panels exactly the same, and have a way easier time mapping the pixels to the overall display. Although the total number of LEDs is less than the maximum allowed by the PP, it is far simpler to program large LED matricies if you know your individual units are the same (particularly if you want to do video / picture display).
