Re: Break out board (GPIO, SPI, I2C, and UART)

It looks like it would be straitforward to make a board that remaps some of the R-pi pins to an Olimex compatable UEXT connector. This would give you hardware access to a variety of boards from Olimex, but drivers would need to be written.

Re: Second Ethernet port needed!

There are also SPI to ethernet chips that it might be possible to hook to the gpio connector. However, they seem to be built to give a microcontroler some ethernet rather than speed. (But they would not contend with the USB bus.)

The alpha board is already running Debian, as mentioned in the blog here and various forum posts. Other than the GPU firmware and perhaps some drivers and a custom-compiled kernel, it is standard Debian AFAIK.

Re: USB to PS/2 adapter support

It would depend on your OS and how it is configured. I'm pretty sure Debian supports them, but since the alpha version demo seems to be using a custom-built static kernel rather than Debian's modular one, it might have to have the driver added and be rebuilt.

Re: How much is a local keyboard / mouse ...

The 1W is for model A with nothing on USB. The alpha version was measured at 2.25W, but this may be higher than the production version. Also, each USB port can be asked for 2.5W. So 1A @ 7V is reasonable for a model B board.

Re: Turn Raspberry Pi into a P.L.C (Programable Logic Controller) Advanced

They have said elsewhere that there will be about 16 GPIO, two I2C, I2S, and SPI on headers. Exactly what and the pinouts have not yet been decieded, it will wait for the final board layout. There is a seral port on 4 solder pads in the alpha, I hope it goes on a header instead.
