On the Macworld upper deck the creators of Liquidspace have set up a quiet and unique workspace for editors and attendees here. It’s a demonstration of the power of the company’s iPhone and iPad app and database; the database tracks availability of more than 250 meeting places around the US. The space pictured is in Sacramento, and you can book it for a fee that Liquidspace collects via credit card. Some meeting spaces are fee-free, such as local libraries participating in the meeting space network.

Most small business providers have had a constant need for a meeting space away from the office. Especially when that business office is a home office. Starbucks or Coffee Bean & Tea Leaf are the obvious options. These are, of course, poor places to Skype into a meeting, given the noise or the lack of privacy. if you’re on the road and away from a hotel, Liquidspace has a solution. But for $50 or more for the hour, if the budget allows, you can reserve a private space including amenities such as wifi, presentation gear, or even enough room to host a group of 15 colleagues or prospects.

The Liquidspace app is free and becoming a member lets you book spaces and get check in passports for exclusive use of a space — or just a $4 seat at a spot like the quiet workspace next to the Caltrain station in San Francisco. Of the 250 spots available now, 150 are in the Bay Area where Liquidspace is growing up.
