This sounds like a silly question (and maybe it is), but I'm wondering if anybody has a package or framework suitable for distributing firmware updates? That is, suppose a project based on Arduino has gone production, and a new version of the firmware needs to be released. If I leave the boot-loader, the upgrade is fairly simple -- I can distribute avrdude and my HEX file -- but is it simpler even that that, like, package the hex and avrdude using this tool, so the end-user need only run a EXE, select a serial port, and click "GO" ?
