This is not a bad thing. In the past we thought nothing of running to the airport at a moment's notice to go visit a client or prospect. There was practically no consideration to the excessive costs in terms of time and money (not to mention massive carbon emissions) - that was just the way it was done. But the deep recession we are facing changed all that fast. Luckily we have the internet and a number of very good collaborative technologies that allow businesspeople to communicate, share, present, sell, market, support and train - without the enormous cost and hassle of travel. On-demand presentation solutions like Brainshark, plus web conferencing, video, telepresence, mobile devices, social networking are outstanding tools to "get the job done" fast and efficient. It also lets us spend more time with our families, which is something we can all appreciate.
Don't get me wrong. There are instances when sitting face to face in a business meeting is essential. We just don't need to do that all the time.
I'd like to hear how your company is using alternatives to solve the challenge of travel restrictions.
