I like Logmein rather than Hamachi product because (if my understanding of how it works is correct) Logmein takes up very little bandwidth. I don't like to leave traces of what I am doing on other computers. I don't really want to be part of the network but just virtually hijack my computer on the network. In otherword, the only thing that Logmein does is send screenshots to your offsite computer and sending back keyboard instruction to your computer. There is no files or digital information going back and forth except for the encrypted screenshot images. Thus, nothing is really left behind on the hospital computer or elsewhere. (Correct me if I am giving incorrect information).
