Whiteboard Addon?

[kalzor]

Would it be possible to write a mod that mimicks this: http://wow.curse.com/downloads/wow-addons/details/doodle.aspx? Doodle is a great addon but it is out of date with no intention of being updated. I tried the Add-on white board continued but it doesn't have limits on who can draw on it and it lacks raid icons.

Do any such mods exist?

Thanks,
Kalzor
