Thanks for that info, but couldn't most of that be download into the VM 
*after* it is running?  Seems to me I'd like the *smallest* VM and then 
have a way to load things into that standard PC.  But maybe I'm thinking 
wrongly?  If so please help me get it right.

I've looked at (or tried) laz4android and fpcup.  Seems that such an 
approach would work much better on a "standard" PC?
