There are some similarities. The main difference is that Wine is mostly in-process whereas, in this design is mostly out-of-process. I'll add a section on Wine to the "prior art" section of the doc.

Disclosure: I wrote the doc linked above.

Yeah, though a more direct analog might be FreeBSD's emulation layer: https://docs.freebsd.org/doc/9.0-RELEASE/usr/share/doc/freeb...
