I am completely unclear as to how to set up a remote computer (work) to run the slingbox.

 I get the impression that any computer I want to use has to originally be set up locally with the slingbox on the same network.

If this is not the case I cannot find the information on how to set up the remote computer and the information from the slingbox that I will need (presumably the finder ID)

Do I just take the software disk to work and run it and at some point it will ask for the finder ID just like my home install?  Do I just download software from the slingbox  website?  Or can I just access a webpage and enter my slingbox info to watch.  I was under the impression when I bought it that I could access it remotely from anywhere and any computer.
