Hello,
This is probably a silly question, but I was curious why there was no such thing as an accessibility web proxy service on the market (I'm thinking about a web proxy server sitting between the user's PC and the server, that fixes and enhances html code on the fly, before it is interpreted by the screen reader on the client machine). 
With a large enough community of subscribers, wouldn't such a service be able to address common pain points for blind web users like optimizing bad html, solving captcha, making popular hard-to-access websites accessible without installing scripts? Or even augmenting web pages (adding summaries or image descriptions when needed)?
Anyway, I'm sure others have explored this idea before (I have found a few academic papers mentioning this concept); what do you think are the main reasons it doesn't exist?

Thanks!

Julien
