For what it's worth, I chose "Posix" because it refers to the API rather 
than to a subset of systems that support that API.  But I agree that 
both are sufficiently general that they could be considered equivalent.

I think technically, the "Unix" moniker refers to the two derivatives of 
the code originally developed at Bell Labs: BSD Unix, and AT&T Unix. 
The other versions are Posix compliant, but not actually "Unix."
