I have found that the rollable silicon keyboards can easily be modified to be turned into a really nice hotpluggable usb interface for OneSwitch.
Tutorial here:

If using this interface with my AutoStart version of switchpup (which uses SFRs new keyhunter script) it puts total control in the hands of the disabled user - without anyone else needing to do any configuration for them.
EDIT : (The latest Radar_firstrun version includes keyhunter now also)
Pups that don't have the keyhunter script will need a small manual change made to the "event" setting in OneSwitch. Details are included at the end of the tutorial.

The number keyboard is exactly what I did when I made my first switch interface.
I also had luck using one of the membrane type keyboards and lightly sanding off the super thin layer of insulation (if it is even the correct term) on the ribbon tape to expose a little copper and then soldering from there.

For anyone who might someday need this sort of adapter I just found an interesting site that offers photos of hundreds of "accessibility" switches that could be used to connect to the keyboard/keypad adapters:

Seems as if the 3.5mm mono connector is a common choice so that is a happy coincidence.
Camera switches used by skydivers are another option:

Also found a site that uses the "oneswitch" name to promote their disabled assistive activities and products, so I'm hoping they do not feel our use of the name encroaches on their activities: http://www.oneswitch.org.uk/index.htm

Added another tutorial to my third post above - it shows how to use a "rollable silicon" keyboard as a donor to make a hotpluggable usb interface for OneSwitch.
This is a very easy, cheap and effective mod. (More effective than the numeric keypad mod which I need to improve due to a design oversight)

Cool I hope I saved mine, a new puppy (real dog.. not linux) teethed on one I had, Now if only I could find it. Most likely placed it in the rubbish-bin.
Still looking for my golden cache of soldering irons. I've used to have many and have not found a single one in the months since we started this project... Did find my 7th grade report cards, was not as good a student as I thought I was
