Just to clarify, the final goal is to allow users to connect the JTAG 
port on the AVR directly to the parallel port of their development PC, 
not to emulate a JTAGICE with a separate PC. Ideally this would be 
packaged as a single executable/script that the developer runs before 
their other devel tools, much like they power on the actual JTAGICE.

AVR Studio / AVARICE would connect to an emulated serial port on the 
development host, interfacing with a simulated JTAGICE, connected to a 
physical AVR though the parallel port, all on the same machine.

As for the use of simulavr as an ICE - this is mainly to provide 
something physical for those learning AVRs to play with, such as 
switches, LEDs, and motors. 

It's not intended to be more efficient or to be used in actual 
development, rather it's to allow a teacher to tape together two 
servos, a LED and a phototransistor and teach a class how to make this 
'robot' follow a line. It's also to allow those learning AVRs 
independently to build something physical without having to buy any
