I think "on the platform of the users choice" is too strict and also
undefined.   What if I said I want to use the "GO" os. Or Symbian. 

On the other hand, saying that something is accessible because it will work
on just one OS and with one piece of AT is also not appropriate.

Rather than setting rules like this -- we need to figure out what is "good
enough" and set that as the line.   That will generally need to take place
on the technology specific checklists.  Which is why they may need to be

Need to think about this.

There is one big catch, is that the proprietary technology needs to meet
WCAG 2.0 on _the platform of the users choice_. 

When a proprietary technology allows you to meet WCAG but only for users
on using a given operating system (say you have to be on Windows) then
the effect is a lot less accessible then the page was WCAG conformant
using a W3C technology.

Also note that in poorer countries free platforms (read Lynix)are
starting to take off in schools ect. It seems a bit limiting that to
read a website you may need an expensive operating system.

Side note: Someone needs to create an open rapper for API's to the
operating system and platform. I am not sure though that it is the
