This year VON turns 10, so it's a bigger deal than usual. If you've never been to VON, I'd urge you to go, if not just to be part of a pretty special anniversary. Nobody has been as strong an advocate for IP communications as long as Jeff Pulver, and this would be a great time to show your support.
And if you want to hear about it direct from Jeff himself - he'll tell you via video!
I won't be hard to find, and will be doing my part on a few sessions. I'm moderating two panels - one on Open Source, and one called Hot New Apps (the link isn't ready for this one yet - it's on Thursday at 10:30am).
I'm also participating as a speaker on the Industry Analyst session, which I always enjoy doing.
