The problem with screen sizes is part of that "absolutely fundamental"
issue that I mentioned.  A desktop thinks (or usually thinks) it has
control as to what appearance, like screen size, is presented to the user,
or at least it should know what it is and be able to arrange things so that
the user sees a usable desktop.  In my experience, the remote desktop is
almost always both clueless and powerless, and it will be only  by chance
that you can see and use everything that you need to see and use.  Even
Windows rdp breaks itself periodically, even though it is glorious when it
is working.  Windows fiddled with services for Unix, but clearly realized
that, in the hands of a power user, SFU reduces Windows to a mere display
manager.  You can now set up an x-server and an ssh daemon under Cygwin,
and both Cygwin and processors/graphics cards have become mature enough
that it is all usable.  *Then* Windows becomes a mere display manager with
a working flash, and away you go, even if you have to use Chrome under
Windows to display some media.
