Depending on the memory needs of your application, 64k should be
doable, at least for a basic IP stack. Do you really need TCP and
UDP? You surely won't need "advanced" tcp features like the more
complicated flow control algorithms, window scaling etc.
There are people doing a webserver in about 1k of code
(http://d116.com/ace/), on a Lego Mindstorm or even a C64
(http://www.vnunet.com/vnunet/news/2118399/commodore-back-web-server).
(Yes, I admit, they don't do eCos).

Markus
