I would like to be able to have "identical" Picasa installs on two (or more) PCs. Essentially my use case is this:
I want to bring my hard drive with a large number of photos away with me, plug it into my laptop which has Picasa installed, and make albums, star photos, etc.. Then I want to plug it into my desktop at home, and see those same albums & stars that I created on the laptop.
I guess this means either: a) having all metadata stored on the external drive, or b) coming up with a reasonable process to transfer metadata between machines whenever I do something on one of them
As far as I know, by default, metadata is split between the install directory (e.g. c:/program files/...) and the directory where the photos actually are. Any suggestions?
