I have written a Wikipedia bot that is highly portable. It relies on
libcurl, so I suppose it's only as portable as libcurl is. Yet, I have
had the idea of porting it to an embedded architecture. It's not
inconceivable that it could run on a 16-bit size_t machine.

Though, as you hint at, if the bot wanted to do any serious editing, it
would need to be able to store a whole Wikipedia page in RAM (up to
2000 kbytes), or be able to stream it as a file.
