In the tradition of Phileas Fogg, hero of Jules Verne's 1872 novel, "Around the World in Eighty Days," Rebecca Campbell is setting out from London today to go around the world in 33 days.

This isn't a race with Fogg. The 26-year-old London resident, a native of Sydney, Australia, dubbed the "Skype Nomad," isn't going for a time record.

Rather, Campbell is showing just how mobile Skype is as she covers ground in 15 countries. "It's all about perpetual motion to show how truly mobile I can be," she said.

She'll be hopping from jet to rickshaw and bumboat in Singapore to a Fogg-esque hot-air balloon over the Alps in Austria, to gondola in Venice, a boat cruising the Yangtze River in China, cable car in San Francisco, dog sled in Alaska, the famed cross-continental Indian Pacific train between Sydney and Perth in her native Australia, and a boat ride across the Baltic from Sweden to Skype's supreme HQ in Tallinn, Estonia to finish up June 6, "D-Day."

The adventurer even is going sky diving--make that Skype diving--in Cambridge, England.

You can get a peek at her itinerary at YouTube.

Campbell, a freelance copywriter/art director, who has been in London for the past year, said she will be in motion constantly. "I won't be staying in hotels. I'll only sleep while I am moving," she said.

Campbell will be Skyping in the air, on the water, in deserts and in dense urban jungles.

She 'll be traveling light: only the clothes on her back, a few extra garments. She'll be toting backpack small enough to fit in the overhead compartment on a plane. The backpack will be stuffed with various Skype-friendly phones, a laptop, video and still cameras, and cables and chargers.

While in Australia, Campbell, the self-described "Sydney Girl," will reunite with her dad, mum, boyfriend Matthew and shiatsu Mopsey. The Skype Nomad has kept in touch with friends and family in Australia via Skype video calls and audio calls.

In most of the world, she will be able to use the 3 Skypephone for easy access to Skype. That technology is not available here in the U.S. Campbell said she will stay in touch in the States via Wi-Fi via Skype Wi-Fi phones and a thin MacBook Air.

Rebecca will meet up with Ed Gallagher, the blind San Francisco adventurer, who has used Skype as his "eyes" as he captains a boat in San Francisco Bay, rides a bike, skis and navigates the aisles of supermercados in the City by the Bay.

Ed and Rebecca, whose previous US. visits include a Disneyland trek as a kid and a recent stay in the Big Apple, ought to have plenty to discuss about Skype mobility.

Highlights in the Nomad's United States leg of the journey in late May, hugging the Left Coast, include an RV trip from San Francisco to Seattle, a revolving restaurant in Seattle, and a dog sled in Alaska.
