I just happened by this chip which looks like an easy interface between USB and JTAG: http://www.saelig.com/ft2232c.htm They claim to be able to program FPGA devices w/ JTAG w/ this device. -Mark

If you do some work you could make it work. However, the result would be so slow that it would be useless. There is huge latency in USB, and the JTAG code must do everything step by step at the parallel interface.

Fast USB debugging is in the works. The hardware tool is a little more complex than the very simple parallel port tool, but should still be pretty cheap. As you said, there is no choice. The parallel ports have already disappeared from most notebooks, and they won't be on the desktop machines for much longer.
