Looking at the MySQL deal. Looks like I'll have to change the default data location to somewhere on Dropbox following this guide [stackoverflow.com]. I'll probably use something like Navicat as well.

I can see how this would work on the Mac Pro, but if I were to try to make entries with the MBA or even iOS, would there be any conflict? Do I need to install MySQL on the MBA as well, or just Navicat?
