Any chance of this being re-programmed into a JTAG wiggler that works with the other publicly available tools?
The FDTI chips are not really that good.
Something that can actually work properly with complex designs that implement SCAN bridges...
Why not go for a Bus Blaster (http://http://dangerousprototypes.com/docs/Bus_Blaster) instead?
Because like many other people I already have the PCB..... why pay another $45+P&P for something that is potentially way less intelligent...
Possibly because developing that might cost you more than $45+P&P worth of your time? There's no reason why it can't be done, other than the fact that someone would have to develop it.
That said, a scan path linker shouldn't pose any problem for an FTDI chip - the software driving it is another matter though.

Er.... You could say that about any open-source product........
That's pretty true - Alas, I've found that using open-source products can sometimes be an exercise in fixing them.
busblaster is using an cpld, should be possible to port the jtagscanner code over to the fpga I guess?
And, while at it, get some ideas from the JTagulator, which uses an propellerchip to do the same, to find jtag with up to 24 wires.
