Hey, thanks @mittense for linking our GitHub repo on your page - that is amazing!
We are definitely considering releasing the full source code. But for now, we are mostly interested in getting some feedback from you guys (see post above). If nothing else, at lest we will provide the source code and technical support to serious developers for a fee - we will definitely not lock anybody in.
I should also mention that the** current released binaries of StreetArch are provided free for commercial use** (we will not collect any royalties for this release).
