Don't know about the typing part - but perhaps some combination of pillows (like the semi-circular kind people us on airlines) + DIY constraints on head movement could help? In any case it's definitely worth investing some serious cash into, given the (very severe) risks that will follow from not having this situation corrected ASAP. Sorry I don't have any better tips for you, but all I can say is: "Ouch" - typing (and crappy corporate work environments) hurt for a lot of people, so (for the sake of his livelihood) I really, really hope you figure something out for him. BTW a small grammar fix: title should say "Helping disabled people code more easily", or perhaps "type and code more easily". (Only offering that so your post won't get so quickly overlooked). "Coding easily" doesn't parse, English-wise, in any case.
