I think right now there's a large difference in culture. Square is really hip and tries to avoid exposing 'nerd stuff' to their users, whereas Stripe focuses heavily on API examples etc. Seeing them combine but stay two different 'personas' could be beneficial for both.
The $20/mo base can be a bit much for some usages -- I still have a few $2-7/mo boxes from LowEndBox for various side projects, but for anything I really care about, I wouldn't put it anywhere but my Linode.
There _are_ RTOSes for the Raspberry Pi, but they may introduce their own problems. I don't mind having an Arduino or something smaller in there to handle the light stuff. Even if you want more control than the circular buffer implementation, it's incredibly simple to write a serial protocol to just individually address the bulbs.
If you wanted to minify it, you could have an ATMega on a PCB with just the necessary components to use as a 'shield' of sorts for the Raspberry Pi.
