Thanks for all the detail on the 2.0 philosophy but I'm still not sure I 
understand the essentials.  Would you indulge the following lapse into 
math-ese.

Consider

the set of all user groups U1, U2, U3... with different sets of abilities 
and disabilities.

and the guidelines UA and GL for user agents and web content.

1. Is the goal of WAI to produce UA and GL guidelines such that if both are 
followed in their entirety, than each user groups U1, U2, U3... will have 
available maxium feasible access to all web sites?  Here "maxium feasible" 
means the maxium that can be obtained with current knowledge and technology?

2. And is it completely acceptable to fulfill this goal by providing each 
of the user groups U1, U2, U3,.... with different versions of the site S1, 
S2, S3... ?

If at all possible, please answer with one of the following
- "yes"
- "no"
- "what  _are_  you talking about Lenny?"  <grin/>

or offer rephrasings of a sentence or two (with or without math-ese) to 
which you can say "yes".

Len

p.s.
Also, if this is the philosophy, I don't understand where Kynn's "minimally 
accessible" fallback fits in.
