How to sync your MAMP install across multiple Macs
An easy way to create the symlink for MAMP's "db" folder without having to use Terminal is to use a Mac OS X service called SymbolicLinker, as explained here: http://www.stucktogetherwithtape.com/blog/2009/12/sync-web-dev-with-mamp-and-dropbox/
What I ended up doing was putting my hotdocs folder into my dropbox and changing the path in MAMP to the dropbox version. I than asked a friend to set up a few mysql remote databases for me. This combination has been working great. I have to use Sequel Pro to access the database which is a nice app. I was originally hoping to use phpmyadmin or learn the terminal but those features were not available on my mates server. Hope this helps someone else.
Dropbox has such a small lag too that I have even found myself coding on one comp and refreshing on another comp. Dropbox is worth finding uses for.
