What if there were an attribute to given MIME types, specifiable in
one's .mailcap, called "receiveoutput" or something similar? This
would be similar to how mailcaps are also supposed to be able to
supports "needsterminal" attributes and the like. E.g.:

application/x-csh-exec; my-csh-exec %s; receiveoutput

When the browser fetches a data object of type application/x-csh-exec
it runs my-csh-exec and, due to the presence of "receiveoutput", pulls
the output of my-csh-exec back into the browser as an HTTP/1.0

What am I missing (i.e. what do you want to do with x-exec that that
wouldn't support)?
