I just got actual useful information from Houstonist. This is shocking and, frankly, almost unprecedented.

Near my house, or near-ish, anyway, is something called the Carolina Collective. It’s a virtual office for the self-employed and work-at-home types who may need office-type support on an ad-hoc or less-than-renting-a-space basis, or who crave the occasional water-cooler aspects of office life. I can actually conceive of using this from time to time, especially since it appears to include available meeting space if you become a member.

Casual, ad-hoc use is free. Usage more than a couple times a week appears to mean you need to pony up $125 a month, but that includes nontrivial benefits like access to food and the aforementioned conference rooms. There are other packages available as well.
