Please accept the following comment from the Protocols and Formats 
Working Group <http://www.w3.org/WAI/PF/>

One of the use cases for CC/PP is due to "accessibility" - people who
need some special set of behaviour from their technology, for example
restrictin the number of colours used because they have colour vision
deficit (this is actually pretty common both in classic red-green colour
blindness and for older people who may lose the ability to detect
certain colours, but there are other examples to do with disabilities
like blindness, deafness, motor control, etc...).

One approach that is used by such people is to have some assistve
technology working on top of their browser. This is normally transparent
to the browser itself. Another possibility is that they simply won't see
content that relies on greater colour perception than they have. In each
case, there may be an available form of the content which is appropriate
for their needs, but the specification of a browser profile will not
take this into account.

It seems that a solution is available (@@see the work that Carlos has
done) by setting up a proxy service on the user's machine which
intercepts traffic - for eample adding some more CC/PP information to
HTTP GET requests to cover the particular needs of the user.
