Sorry that I'm late to this thread!

The first question appears to have been answered by others but I will add that even though Infinit is currently closed source, you can build your infrastructure without using the Hub. The Hub is just in place to make it easy to fetch user public keys, network and volume descriptors and endpoints at runtime. You can do this manually using the CLI (--export/--import instead of --push/--fetch).

We're using the 3.x branch of FUSE for OS X and haven't had an issue with it yet.
