Hi all,
Just to let you know that calibre 0.8.5 has a "portable" version, that you can put onto a USB key and run on any windows computer (Windows XP SP3 or newer).
The portable calibre keeps its settings/plugins and of course all your books all within the "Calibre Portable" folder.
Get it from here:

If you use it, let me know if there are any problems.
On a technical note, I was able to get this to work by doing several hacks to workaround Microsofts' DLL loading policies, including a rather cool custom DLL loader
