I checked the homepage. There is no obvious information about the type of license for this, price if any, etc.
"Private beta soon" says (to me) that it will be proprietary, and the fact that the "first class" clients are JavaScript and .Net makes me think the backend is .net based also, which pretty much implies running on Windows server.
This of course is all speculation, but without information what else can we do?
At the very least I would recommend you allow it to work with a full RDBMS like MySQL/compatible or PostgreSQL. SQLite means you can't have online replication, which means you can't make it HA.
