Yes. Although, it's only the header key. The value isn't limited.

That would be implementation dependent.

Well, that's not really a typical case. It would be pretty hard to
use a method that had more than 64k characters in its name. :)

It's more to make buffering easier. 32k chunks are a nice power of 2.

The datagram/udp idea is an interesting one I've meant to think about
more.
