A web 2.0 service that lets you know when a "colleague" is in the same wifi cafe. Aware of itself and others like it, the app gives out your virtual biz card and tells a bit about you and what you do while doing out-of-office work. If you want some comraderie and perhaps some collaboration, you can put up your flag and see who else is up for it. Hell yeah, web 2.0!!!
