I ran a team of up to six trainers operating across a whole county using shared calendars via Lotus Notes back in the early nineties. I don’t think we could have managed any other way as we had no admin support (local Government cut backs) but it worked brilliantly for us. We even arranged our team meetings using it to track down the nearest decent pub to whichever part if the county the majority were operating in that day. With over 60 fire stations, ten big and many small social services offices, five large training rooms in different cities, councillors in every ward and highways, waste management and other teams out on the road almost all the time, anything other than complete interoperability would have got in the way of the job. They called us the e (for electronic) team and we were among the first really USING eGovernment in a big way.
