Accessibility includes far more than just blind and visually impaired users, though. While my mud does provide extra support for blind players, those with learning disabilities or motor/dexterity impairments are probably going to find it less accessible than most other muds (because there's a lot of complexity, and a lot of typing).

If there was just a single "accessibility" radio button with a text box, I suppose you could click the option and then state exactly what sort of accessibility features you support (although I fear we'd see a lot of muds clicking the radio button and then writing in the box "Fully accessible to those with hearing impairments"). But I don't think the four choices would work so well unless you split it up into specific disability types.

Another option would be to have a radio button for "Requires a custom client", although there are very few text-based muds that would need to select it. I think this would be much less useful for visually impaired players, although it could be of interest to others.
