Bosses want to be able to use hit the road when they are out of the office. As far as I know, this would entail having to open port 1677 to the world. Do any of you currently do this? big no-no? not a big deal? looking for thoughts/experiences.

Example, boss hits the road from the office to sync up his laptop, spends 5 hours on a plane flying across country, while replying to emails etc. wants them to send when he lands (or has a connection).
