Optimally, I could have used my digital camera to take a picture, and show it to the pediatrician over the good ol' Internet. Unfortunately, all of my gear requires physical connections to communicate, and compiled applications to pass files back and forth, and human intervention to route things appropriately. This is the first time that I have thought that the new breed of cell phones with crappy digital cameras in them would actually be useful.
Of course, the person on the other side of the equation needs to have the same carrier, or gear and/or level of comfort with the tech to receive the image and attempt to make something from it. Ubiquity is a long way off, and so are the systems/applications we need to allow folks like me to easily send useful info to particular individuals on demand.
