Mandatory webcomic reference: https://xkcd.com/941/I want to try creating long-baseline stereoscopic video of clouds.  In order to do this, I need a pair of webcams I can set up 100-300 feet apart to stream video to my laptop.  I figure the best place to set this up is a nearby cliff, but that means I'm somewhat lacking in the usual computer infrastructure (electrical outlets, wireless access points, etc.)Requirements:Wifi support, preferably ad-hoc mode.Powered from batteries (preferable) or with an external power supply I can replace with a battery pack.Predictable latency.  If both cameras are showing images from a second ago, it's fine; if one is showing realtime and the other is delayed by random amounts, it throws off the stereo illusion.Inexpensive.  I'd really like to keep this under $100 for a pair of webcams; below $50 would be nice.Support for Linux (preferable) or Windows XP.
