That shouldn't be too hard, since the fs-code used by the httpd is already used 
to do that (or at least that's what TI meant it to, I didn't test it, yet).

Yes, it is overkill. Also, I think it's a better example on how to use lwIP if 
you do use the timer framework lwIP provides.

I don't really think so. It works, but it does nothing useful. It's rather 
there to show how it works and to test whether blocking/unblocking works, etc.

However, the ping app in contrib has a socket mode, which could be quite useful.

Hmm, did you plan to just include some existing socket apps here, or use raw 
API apps?
