Hi Richard,

A suitable solution will be to use Chameleon POD (smart parallel port
dongle).
The POD only is EUR 129.-

Our POD is used for JTAG interface emulating (Raven Wiggler ByteBlaster
Xilinx Cable III ...). It is based on reprogrammable logic (CPLD), with
onboard 32MHz osc., and a true 1284 transciever. You can customize the
parallel port as you want.
We have successfully dev. a I2C MASTER CONTROLLER on it.

Our I2C MASTER CONTROLLER can drive a true 100kHz or 400KHz I2C
frequency, but can be up to 1.2MByte baudrate using EPP mode of the
parallel port ;-)

We have our own Windows drivers and can provide you the help for Linux
integration. Also on any windows, you can use portmon driver.

Many poeple forget the EPP mode of the parallel port provide a better
datarate than the USB 2.0 (12MHz) when we you have to control a non
'packetable' application like a small I"C Controller or SPI controller.

We have a nice PCI solution based on FPGA. We have both PCI Slave core
and Win/Linux drivers.

For USB solution, check the new FTDI Chip, FT2232 ... your will be
enable to remote an small ISA based bus. -> but you will be in very low
speeds: 60kbits second :-(

Let me know, for more details.
