Soft or page to sketch with friends?

another caveman

Hi, could anyone recommend a plugin, software or even a web page to paint on the same doc with connected friends? (a plugin to Photoshop could be sick!)
I just tried aggie.io but it doesn't work with all tablets (worked with a wacom, but not with artisul d13)

Thanks
