Pretty interesting! We're gotten quite a few different ideas, stretching what we had in mind people wanted to use Linux for. Home automation, solar power infrastructure, on-board ship monitoring and control, even gaming... and lots more.
Two more weeks left! Please don't be shy. Remember, it doesn't need to be extreme. Our Linux servers are tough, but they're mostly used in homes and offices. Tough is good for normal use, too!
Send in your ideas, and may the best proposal win!
