What about a web-based instant messaging client, where the user types
some text and it must be relayed to the server as it is typed, perhaps
character by character?

There are basically two ways to do a "web application" like that now:
GET or POST with client-side scripts.

My reading of the HTTP spec. says that POST should be used for those
messages, because it's not fetching a resource, it's sending data to a
resource to be processed.

In practice of course, the author will use whatever works, which often
has to be GET for technical reasons.
