Have you seen the Bus Blaster? It is an FT2232 based board which has both ARM and MIPS eJTAG support. The Bus Pirate (also sold by Dangerous Prototypes) also has the ability to perform JTAG, but it runs much slower (like, 10 bits a minute or something ridiculous).

    Bus Blaster v3 look interesting, will definitely consider it. Small drawback is it have no protective enclosure, so it should be done by yourself.

I have used the following devices successfully with OpenOCD:

The Bus Blaster is compatible with OpenOCD as it was a jtagkey and therefore I think it will satisfy your needs accordingly.
