I am just getting started in Factor, and am partially drawn to the ability
to do cross platform GUI development, but I thought I should mention a cool
ability to ship a self-contained HTTP server using their easy to use furnace
library. It could launch a browser to itself on startup and produce the
output format file locally. If you already do web programming it shouldn't
be much of a learning curve.
