Finally, I think people have understood my point now and to respond to a few of the recent replies, I will start with Ian. Yes, the situation all seems very gloomy and damp for Ben as well as others who been through what he has. With regards to the paid professional concerts, yes there are no good fix-it all solutions, but I would of course go with which ever option would be the least damaging in terms of artistic integrity, reputation, career, etc. If that means to preserve integrity (not performing due to great risk of sounding horribly) and taking an early retirement, then early retirement it is. Now, if those that play on, I would suggest doing as well as he/she can humanly possibly do with the repertoire or amended repertoire.
Now, onto Bob's responses.
I do partially agree with one facet of that if one is faced with whatever one has (current limitations), then one has to do the best one can. Such an example would of two virtuosic pianists (A and B), one has suffered an injury that has set back his dexterity significantly and he is unable to pull off a Chopin Etude, whereas the other one is able to. However, the one with the injury instead, goes for an Chopin Prelude or even easier repertoire and with the limited repertoire, A is able to perform THAT specific prelude to concert standard, then that is still a better situation than none at all. Hence, for both pianists, that once were playing the same or similar difficult repertoire, they both would produce good music. It is unfair to compare the same Chopin Etude between the two (A is injured and B is not), but reasonable to compare A to his Chopin Prelude and B to his Chopin Etude.
I'd still go with 'What they can play should sound good. If they can't physically play a standard piece, they can't play it. That's how it is.'
*DING DING DING*
This is what I'm looking for and hence it is a reasonable expectation especially in professional performances.
Regarding Ben Folds, yes I agree, he should either be given a rescheduled jury exam, incomplete grade, exempt from the jury (and probably replaced by another assessment), alternative exam, or other accommodations.
And for the other guy, Landon Weeks, yes you are correct, that would be a different situation. Not trying to rip on Landon, but (from a honest assessment) I also believe you are correct that no music would want to take him in, for that. As far as the ADA and the litigious society in America, your scenario could be true, and realistically speaking, even if the school does take him in (to be PC in this current society), finding a job in his field would be difficult (I hate to be blunt but I don't know how else to put it) as the jobs are limited in the field, then compounded with the factor that he has a disadvantage compared to the other graduates in that school. So, yes even if people like them are able to go through a music school, in reality, the music market would not accept him (not because of anything personal against him), but because there are many other prospective candidates to take the job hence the employers can afford to be picky.
On to dcstudio now.
DC, I don't think I know of a competition specifically or been in a festival where that happened either, but I do know that there are probably instances of that happening out there in the world.
Also, I'm happy that the drummer got a standing ovation and good reception of his performance. I wish to see more cases like this.
Finally, back to outin

I suppose one could just let those insurmountable pieces be laid to rest (one of the many work arounds), or of course play what one is capable of playing.
The last sentence is one that I can agree with, and while it is a loss to sacrifice one's favorite or coveted repertoire, if one wants to salvage integrity, then that could be a possible trade off.
