Sorry to see no one had any info to help you on this one. Did you ever work it out?
I'm considering a few different photo managers for my personal collection. I don't use a Sony camera, though ...
EDIT: Looks like I'm not going to be the one to compile F-Spot. It requires Mono, which is a bit time-consuming to compile (search forum for other threads).
I'd be interested to know what you/others are using for photo management.
