Any input?
Yeah, I can imagine many people using that capability. A friend who does electronics workshops had talked about wanting to program kits with a mobile device, too. I think the first requirement would be USB host mode which most Android tablets have and also more phones now too (like my Samsung Galaxy S2). The second requirement would be installing a Linux distro which could run avrdude. The XDA Developer forums are good place to look for Linux chroot install instructions for a specific device: http://forum.xda-developers.com/
