What I'm advocating is that 

A) you can *always* get a 256 byte frame through.

and

B) that all software SHOULD be configurable to allow 16KB frames.

No more, no less.

And as I analysed in my previous email:  In all the cases where
Jeff has an opportunity to do that, there is almost certainty that
it will always work.

The one case I can see where it might fail, is if Jeff tries to access an
"intelligent lightbulb" at edison.example.com, after example.com's main
websever stuffed his browser with 14 kB of cookies.

That's a corner-case I can live with.
