I have created a (mobile) web based "remote" for Eos. I built it mostly as a learning experience, but I think it turned out pretty useful. Currently it will display the current command line, a small keypad and a cue list. It is designed primarily to use with a mobile phone, but works fine on a full browser as well.
I've just started using Eos Nomad, so I'll likely be adding features, but I think this will work well for our theater with conventional fixtures.
