I think it would be both interesting and useful to have a working codebase and example that could be used with microcontrollers.  This project's aim isn't to produce something with a superior efficiency to current solutions, but if somebody does want to try going down that path it would be nice to have a codebase and/or ideas to work from. 

I think something that could use one or more arduino's to do the calculations in an efficient manner would be a net positive for other projects as well.
