i've written my first app for the infocast which also happens to be my first flash app. it's a control panel for sagetv.  i built it with flashdevelop using the project sample for a Chumby2MPD controller ( http://goo.gl/x7Tyl ).  it's still a work in progress, as i figure out better ways to build the layout and actions.  i've got a screenshot of the interface over at cocoontech.com ( http://goo.gl/i9YPo ) and my post over there also has a link to a youtube video of the interface controlling sagetv.

i was able to upload it as a private app on the chumby site so i can run it on my infocasts without having to kill the control panel and run the app manually.
