i use logmein all the time.  i have the free version so am limited to what that provides.  i have a home office and two other field offices on construction sites at locations in different parts of the state.  the only shortcoming is that the other computers have to be up and running to log on to them so i find myself leaving the three computers running all the time so that i can access info from each if i need it at any time during the day or evening when working at home.  It is a very good system and being free makes it that much more inviting. i would be interested to know of other systems that are out there if anyone else knows of any that are comparable to logmein.
