Actually... I think Eye-Fi is on the right track. I'm still looking to pick up one of those for a decent price and see how well it works. With the newest version, you can have your pics sent to your phone from your DSLR in realtime. Thus, quickly uploading pics taken with your DSLR to Facebook/Twitter/Flickr, etc...
I had not heard of Eye-Fi - Thank you! I googled it and saw a video about it at http://www.eye.fi/
What do I look for to know if it is the latest version?
