My understanding, which is not very complete yet, says that the
difference between console and gui apps is just in the way they start
up; the console app can make the same use as graphics as the gui one.
So this sould work fine. It's likely to be a bit more work than it
seems to factor the code so the io goes throug callbacks in the front
ends, and the design of the graphics may need to be modified if graphs
are to coegist with a standard console or an emacs console, but it
should work fine.

The one point to keep in mind though is that console apps are possible
on Win95 and NT but not, I believe, on Win32s.
