Now we know where to obscure technical question from a few days ago came from...

Am I right in assuming the CBR file was generated from the PDF file and does not contain additional information or higher resolutions? The size difference is quite substantial...

OMG, Looking at that image I can't help but be reminded of a certain scene from "There's Something About Mary"... They should've chosen a different color for the thing...

With regard to synchronizing data between your home and office, I've pretty much have been doing the same for a couple of years now using Unison.
I'm also synchronizing my dotfiles and other customization data, this makes it a lot easier to settle into a new machine.
However I must wonder about synchronizing video, I only do that for mail, documents and such, wouldn't it be more efficient, bandwidth-wise, to simply torrent the movies back from somewhere if you ever need to?
WRT the NAS box, I couldn't find many details on the Netgear site, is it even possible to make it talk anything other then CIFS?
