When not practicing how to waddle or wear a tuxedo, he works with eZ systems AS as their managing director for North America; with the Mozilla Foundation on various community issues; and volunteers with the Free Software Foundation's Compliance Lab.

At Novell, Stone has responsibility for all engineering, support, marketing, product management, alliances, global sales, and consulting. Stone will be instrumental in driving Novell's one Net vision forward, and is focused on reasserting Novell's technology leadership moving into a web services environment.

Novell has also begun shipping Nterprise Linux Services, a series of network services providing value-add on both Red Hat and SUSE Linux.

Stone has a degree in Computer Science from the University of New Hampshire and attended the Executive MBA program at the University of Virginia's Darden School of Business. He was named a "Top Ten Entrepreneur" by Red Herring for 2001.
