I just saw a demo for a new online communication service called ddsWebLink. You can see it here: [1]
I have long contended that the final element of a truly paperless office will be Internet communications. What ddsWebLink is trying to do is provide a secure system for sending information about patients to colleagues and labs. They have done a good job so far. There is a long way to go. Never the less I am excited about the idea. Look for them to hit the market early next year.
