Being someone that may soon be in a remote working situation, I'd be very interested to hear what tools you (and others) find crucial for your day to day remote communications. I am not an engineer, but in more of a producer role so personal communication is a large part of my day to day work. I'm wondering if I can get anywhere near the level of communication that I've grown accustomed to, working onsite. I'm obviously familiar with Skype/iChat, Basecamp, Campfire (we use these tools extensively even though we are in the same office)... Just wondering if there is anything else that helps more than these tools, or if its just a matter of being very diligent with them.
