Many of us have more than 1 dropbox account for various uses, personal, business, hacking , etc.... No surprise that I'm not the 1st person who wants access to more than 1 at the same time. After a little research I found a website with details how to accomplish it using bash and (optionally) Automator, http://theterran.com/blog/2012/6/14/use-two-dropbox-accounts-on-one-computer.html Because Dropbox is not officially supported on the PPC you have to use the version modified by @Czo from this thread. During my testing it's clear that Czo's version checks for any running instances of Dropbox at startup. That means if you want to run two copies you must start the second account first. Here is a screenshot showing my G5 with 2 Dropbox accounts active at the same time!
