Hi Ted,

What kind of simulation speed can you achieve?  I imagine using python 
wouldn't be all that quick.  Whatever is finally included with gdb will 
most definitely require as complete on-chip peripheral simulation as 
possible as well as the ability to add off-chip devices (e.g. LCD display) 
virtually wired to the virtual AVR.  Flexability will be the prime 
requirement (that includes OS independence), speed secondary but important.

Anyone else got any thoughts on simulators?  Bruce?
