you are welcome!!
if you go logmein pro, you only need one license, I would use the manager for that.
if go logmein free, it's a little more steps because you need to remotely control one computer at home and upload the renderings to a FTP or something similar, after that you have download them from there....I have logmein in my Iphone, so I can see what is going on when I'm out of my office
another good tool to control the farm is RefaMo, you can control them, see the status of memory, proccessors, disk, etc.... you can turn them off, and run batches, so if you need to turn off or on DR in vray, it can be done in one click all the computer at once.
