Oh my god. I love this!
I've been waiting for a simple polished solution for this for years and years. When skype came along and then we got skype extensions, I thought they'd solve this, but oh no. Every solution that has come out so far has been mediocre at best. I'm glad someone decided to tackle this properly.
I haven't had chance to try on iPad, but from the homepage it seems it'll work fine there as well?
Haha thank you! Yes it works fine on an iPad - in fact better than an laptop because using a finger to draw is so much more fluid and intuitive than a mouse or touchpad. Here's a video of me using WhiteboardFox.com to draw with my iPad: http://youtu.be/MDEHFHG1l3Y?t=1m10s
And yes I had the same thoughts last year when I was looking to work with a remote programmer: "Surely, surely someone has a half-decent solution?!". At the time, no. Now, yes :)
