Would someone be so kind as to add this to the wiki somewhere?

Short summary bout what i found out until know:
The best looking options are the JTAGkey[1] and
JTAGkey-tiny[2] from amontec and the USBJTAG[3] board
from Hubert Hölg. All three together with the Open-OCD[4]
software package.
All three systems use a FT2232 USB to Serial adapter
chip in bit-bang mode.
Unfortunately, i didn't had much time to look up what
Open-OCD exactly does and how it could be used. As soon
as i have some time, i'll check it out, order either
one of the JTAG-key's (probably the -tiny) or build
myself a USBJTAG board (though this would cost more
than the JTAGKey-Tiny).
Whether these boards can be used to programm a Xilinx
or Lattice FPGA is still an open question, but it should
be only a matter of software than anything else.
