I was thinking of trying to get org and microsoft exchange talking to each other via soap-client.el and exchange web services (ews). Ultimately it would be nice to have a route into the corporate world of exchange, outlook, entourage, and blackberry where so many of us are forced to live.
My first goal is to link org TODOs to exchange tasks in some simplistic way that allows two-way syncing. If that proves feasible, perhaps calendar items could be next. Does this sound useful? If anyone with elisp or web services programming experience is interested in lending a hand, I am sure to need some help.
