"the brain" and their costs (fenn):
ATmega48 20MHz microcontroller, easy to interface to sensors and relays; can be configured as an insecure webserver and/or USB device with the addition of some inexpensive external electronics; intermediate difficulty to program $2.58 @ digikey
AT91SAM7S256, an ARM system on chip with integrated ethernet and usb "slave" support, rather advanced programming/development, might be able to implement encryption protocols if you knew what you were doing $12.58 @ digikey
makezine controller; same as above but already soldered and comes with a simple operating system and connectors, fairly easy to program; you'd have to make sure that the included AES encryption code is actually secure $109.00 @ http://makezine.com/controller
TS-7200 full blown linux server running debian, in a tiny package, easy to program, perhaps too easy.. but you can use ssh and ssl for encryption $149 @ http://embeddedarm.com/products/board-detail.php?product=TS-7200
i should add Arduino to this list; basically the same as atmega48 but already soldered to the board; with usb connector $30 @ sparkfun + $45 for ethernet module
Tom: What about the linux "wall wart?" http://www.linuxdevices.com/news/NS9634061300.html ben: it has no i/o so you're back to square one (equivalent to a laptop with USB port and ethernet)
