Y Combinator-backed Floobits, a new startup allowing two people to write software at the same time on the same codebase — known as pair programming — is officially launching today to help better connect remote developers and distributed teams. What makes this company’s implementation interesting, however, is that instead of requiring developers to use a web-based editor as many pair programming solutions today do, Floobits users can pair program directly within the text editors they’re already comfortable using through the installation of plug-ins.
