I presume that the source package would make it fairly easy to build our 
own wheels.  Even if it didn't provide support for a given platform 
somehow, at least the 'automated' build would be available publicly for 
modification and patches could be submitted (and maybe accepted).  That 
would be a great step forward in my opinion.  The lack of any reference 
builds has certainly been frustrating for me (or I'm just silly and 
missed it).

As for the current "wheel build script" it sounds like you are saying it 
is, and will remain, private?


P.S. a build of the Designer plugin meant for use with whatever wheels 
are published would certainly be nice as well...
