I seem to spend an inordinate amount of time trying to access data and media hosted on a machine that I'm not near--I use Dropbox, LogMeIn, Timbuktu Pro, and Back to My Mac. But now I must add one more tool to my arsenal: Yazsoft's ShareTool. ShareTool lets you securely share, over the Internet, all the services on a particular computer, as well as all the services that computer can reach on its local network.
