The ClueTrain Manifesto was published almost 8 years ago. There is now a nice slide show of it here. If you are in marketing, you are living in a networked world. Which means building a marketing team must be geographically agnostic. Think about it, if you are communicating with a networked market and can only work in a physical office with line of sight management, you're not going to be very successful are you?
Saw a great article about running a virtual company. At my last company the entire sales and marketing team was virtual. We stayed in touch constantly, got things done, but left the door open for disagreement. But it was always around the best way to achieve the goals, not the goals themselves. So having clear goals and consistent discussion (via email or voice or IM) is the key to creating a powerful team. And we only met in person once a year. And it worked.
Some good tools: A virtual office to answer the phone and provide physical space on demand when you need it. Also a good real time collaboration tool for working on documents ad-hoc (I liked it because Windows and Macs both worked great on it). And finally you need a virtual gathering space to keep all the project documents and notes. This looks interesting and in the past I used Web Collab and installed it on a hosted web site for $10 / month (had to fiddle with the php).
