Mobile open source player Funambol is certainly giving us plenty to watch these days with its Affero GPL licensing, its use of ad-supported mobile phone access to email and general bet on mobile open source software. Like an audience watching the tightrope act, we’re observing intently (Funambol translates from the Latin words funis (rope) and ambulare (walking) to give us the company name and tightrope walker logo). I recently met with the company’s VP of marketing, Hal Steger, who demonstrated perfect balance drinking a cup of coffee and talking at the same time.
