I’ve found these two different tools while on my adventures around the internet. Gliffy the visio killer? While its nice, Visio has alot more images/items (whatever you want to call them). However it is a nice product for doing quick diagrams and one day I drew up a proposed network design for home. I’ll upload a copy (when I can get it off my laptop in work).
I’ve only discovered Imagination Cubed from GE now, and i’m not too sure what to make of it. The fact you can invite other people into your whiteboard seems promising and I think this is the only web-based application whiteboard I know of.
Yup Gliffy looks sweet. It’s certainly a good start.
