I have posted the slides and the source code for the xfire integration demo that I presented on 4/5/06. For those of you who were not in attendance, this demonstration's purpose was to introduce XFire and how it can be used to expose a web service. Rather than the typical "Hello World" example, I decided to integrate the service with a microcontroller, whose purpose is to display the temperature of my basement.
All of the source code and slides can be located here:

I have not included all of the rxtx libraries (the .dlls) as their installation is platform specific. The hardware schematic is included in the ppt slideshow, if you need a detailed parts list, just ask me.
