Not sure i get the entire context of your question, but my method is fairly simple....and it works for me.
I use Windows 7 at work and a Mac at home.
I have TR program installed in both "locations".
I use Dropbox to store all my files (inc backup / archive).
Each App points to the "data" in Dropbox.
So one data file, more than one usable end points.
Thus if I spend time harnessing the power of "views" and refining/trying things - I usually do that at home....but when I go to work my efforts are there to be used....
Hope that helps...it seems that something similar would meet your criteria of not leaving files at work etc and have access to your list at work. I've missed the question, ask away.
