I'm doing my best not to be rude, but you can't spend hours designing for "everyone with every disability." Believe me, I would...but my clients wouldn't enjoy my bill for 80 hours of work so that a site works in lynx.

You have to come to your own conclusions about who you hope will visit your site, and who to leave behind. Thank god there are no laws requiring special access for people or web designers would go out of business.

On a more personal note, I'm more of a backend developer, so ASP doesn't matter what the client is, as long as data is returned to the client.
