Hey guys, I'm working on a project that I'd like to send out in the field for beta testing, but I'm looking for a way to send updated firmware to the testers to be able to upload without requiring a ton of computer knowledge and without releasing the source code. Ideally I'd like to be able to email a HEX file and have them be able to install on an Arduino Pro Mini with minimal hassle. I've thought about trying either some sort of SD card and second Arduino option, but that makes the project a bit pricey if I send out more than half a dozen prototypes for testing. I was also looking at something like xloader, but it seems like that's a bit hit or miss right now, plus a few of the guys are Mac guys. Any suggestions?
You should check the AVRDUDE command that uploads the hex file.
Works on windows commandline and I guess also on Mac commandline

you can wrap it in a cmd script or so
Package your hex file, avrdude and a one-line batch file in a ZIP and send it out. I do it all the time.
Sounds like an ideal use for Standalone programmer. The ICSP pins can be made accessible?
$48, I can't help you about the pricey part.
