Actually, this is easy!

The flex scanner is already modular - it allows you to override the 
function delivering the data to scan (it's a feature of flex). Right 
now, that funtion is read(). However, *any* function returning a string 
can be used.

The biggest change would be to trigger a GUI redraw periodically. 
However, this isn't too hard either to do every few lines of log text or so.
