Have a look at:
   www.mpeforth.com/usbstamp.htm
   www.mpeforth.com/jtagwidget.htm
The CPLD on the USB Stamp is already configured as a JTAG host. 
The software on the JTAG Widget is a scriptable ARM JTAG 
debugger and Flash programmer with integral ARM assembler and
disassembler.

If you understand the RDI specs, doing what you want should be 
straightforward.
