] In the photo above is the webACE: a Fairchild ACE1101MT8
] microcontroller programmed as a Web server and containing
] two tiny web pages in its on-chip memory. Since the
] ACE1101MT8 is the smallest available microcontroller, I
] believe that this really is the World's Smallest Web
] Server.

This is the platform used in that fly article. This article is a little more informative. I don't really care about the fly. I care about the server. Links to a number of other more practical platforms such as PIC based servers (they are technically larger, but basically the idea is the same). A little digging and you'll find a number of open source TCP/IP stacks for microcontrollers.

This is of use if you want to embed internet connectivity into extremely small devices. The next question is how small can you make your bluetooth transmitter.
