That was my thought exactly.  The daemon on the server is the grunt 
worker, so speed/stability is of the essence.

That is what I was alluding to in my first post.  The SRS does not 
specify exactly what the client is programmed in or how eye-candy-rich 
it is.  ncurses is ok for me as well for console stuff.  I do like nice 
X GUI's, so if one is written, then QT is probably the way to go.

That would be me.  My lab is really old PII's (running at 233MHz). 
Currently a build takes right at 12/13 hours - not too bad considering. 
  I do want the server process to be speedy however and minimize the 
overhead it adds to the system when I really want as much horsepower 
reserved for compiling. not for daemon stuff.
