blphu,
I agree with the advice given above, but I want to clarify something. You said "LogMeIn only allows one connection at a time. We have more than one users that need to access the main AC computer". Can you explain what you mean?
How many users are in office #1? When you go to office #2, how many will be there?
Let's say that you and your secretary go to office #2... you realize that with LogMein, you can each log onto your machines in office #1.
