Help me figure out an Aperture Library Solution

Eventually you may run out of space on your MBP?

I run a MacPro and an MBP and I use the MBP as a mobile machine, collecting photos when I am away from home base (sometimes for four weeks at a time). When I get back I connect the MBP to the MacPro by Firewire and import the MBP Library into the MacPro's Aperture Library.

If I want photos to go the other way, e.g. to take photos to display elsewhere, I'll export the Projects as a Library and then use that on the MBP.
