Stanford U Class Innovation class is using this tool 
https://trello.com/ 

It does everything a sticky-wall does both onsite and online
It is a "cloud-based sticky wall"

It lives on the cloud and can show up on a computer screen or be broadcast on a whiteboard.

Sticky Wall = a "Board" [where you make groups of data in columns
cards = cards, but smart ones with video clips, comments, voting, distribution via email
grouping = make a category and move cards

Best feature: drag and drop cards from anywhere to anywhere.

The class uses it with either google+Hangouts or skype conference calls. Anyone can add or move data anytime; or the board owner can set limits.  

Hope a couple of people try it and share what you see. 
To start watch the short video at Trello.com.
