Create a design where the SX reads the sensors and makes the decisions.  Then just hang an Ethernet module off of it and communicate with it using a serial port.  The SX is just not designed to do Ethernet type stuff.  Some modules to consider:

--  the Parallax PINK (Ethernet Module) is very easy to use and well documented.  I have one of these and they are fun!

-- Netburner board (about $35), but that takes some talent to get it working.  I have one of these too but as the documentation says, buy one of the development kits to go with it so that raises the price.  Once you have the dev kit, things go much easier.

-- If size is important look, at the Lantronic XPORT XE (about $50).  It is about the size of an RJ45 Ethernet Jack and can be mounted directly on a PCB.  Again this will take some talent to get it working.  I bought one of these because I just couldn't resist.  However I'm afraid of it because it has to be mounted on a PCB and if I screw up I just blew $50 (I have committment issues!).

-- There are many, many more out there but again use the SX for the central command and the Ethernet module as a gateway to the Internet.  Putting an Ethernet module on your project is fun and its very kool to be able to access it from work over the Internet.
