Reports from Interbike (the annual bicycle industry tradeshow in Las Vegas) universally indicate that public interest has acknowledged the utility of the Xtracycle Free-Radical.

Commuter bikes and other practical designs are also becoming more visible (Civia Cycles looks promising). It may be that industry folks are paying attention to a small but loyal following, but I'd prefer to think that the demand is broad-based, and expanding. Of course, what I prefer doesn't matter. Nevertheless,

Break out your copy of The Tipping Point, this is a great time to be alive and riding a bike.
