While reading up on the SLiMP3 network MP3 player I came across some mention of Dallas Semiconductor and their line of wonderfully hackable TINI ICs. These little things have ethernet interfaces, Java runtime engines, and webservers built-in, and are ideal for making non-networked devices internet ready. As if we don’t now have enough internet connected light switches and soda machines.
A nice overview of TINI is available.
