Sharing large library of Photos and Videos (currently in iPhoto) in different macs at home currently I have iPhoto on my mac (mountain lion). the library is more than 350 GB (and growing fast). It is only on my computer, but my wife wants to have acces to the pictures too, not only photostream. She has an older mac book (white) running lion.

My idea was to centralize the library (NAS) and solve 3 problems at the same time (space on my laptop, and acces to more than 1 user, and backup of the photos (currently on my time machine)). As far as I know, it is not possible to store the iPhoto library on a NAS... So, what alternatives are there? I know picasa, they have a light app for mac, but aren't there any other alternatives? I don't want to split the library. 

I currently use faces and places... and I would like to keep this features. I also like to share pics with my friends via photostream, but this can easily be replaced with other services. 

Thanks
Have you tried to use something like AeroFS to sync the folder with the iphoto library across the two computers? You will probably still want to avoid making edits at the same time but at least you will have access to the library on two computers.
