Lpc2000

The spec is a level of performance that is significantly higher than
Wiggler-based debugging. 

It would seem interesting to use an LPC with a USB controller as JTAG
emulator, LPC2142 or so. 

The thing I'm not sure about is what the reference points are. 

What kind of traffic is there between emulator and target? 
What kind of traffic is there between host usb driver and usb-based
emulator? 
What kind of software is needed between host usb driver and the debugger? 
What kind of traffic is there between the debugger and this program? 

With "what kind of traffic", I mean, what protocol is used between
these "application layers"...
