This is a very good point:  why are they offering their software for free, 
knowing full well that other people are using it on competitor's hardware?

Yes, baud rates are slower over parallel, although you can get > 1mbit/sec 
on the parallel port itself, perhaps only 25KB/sec when using wiggler, but 
even there, even with a rather large code size of 512KB, this is only 20 
seconds to download...  For most debugging scenarios you won't need to 
download the full size anyway, and if you split your program into modules 
you can get by with only debugging a module at a time, which means you only 
need to load a few dozen KB at a time?
