I'm looking into creating my own app for talking to my Virtual Wiring system. I'd like to be able to change values in the system (like I do using the Device Explorer page), and perhaps read values from the system to update buttons or status in the app. What's the best way to go about this?

VW has a web interface which uses JSON. There's a writeup on how to do it here:
Essentially, you can "get" a JSON representation of the total state of the system by reading from a VW system's "/" page. To create events (change values), you "post" to the system's "/events" page. In the writeup, there are examples using curl (a popular command line tool for interacting with websites). To get a feel for things, use curl to read and write a system (curl comes pre-installed on most *nix systems, and if it's not, it's easy to download and install). Once you see how things work, you can start reading and writing programmatically.
