So I recently found out about Prey Project, you can install it on a computer and it stays out of sight, out of mind until you need it to start tracking. As far as I know this will still work even on OS X in a guest account. I'd like to keep my main account password protected for sake of file security and such. However, I also have read some stories about LogMeIn and people using that to grab information about a thief, maybe a document or picture they've saved on their 'new' computer, and uploading that information into dropbox to gather evidence on this person.. Which would be a better method? Or maybe even both? Being OCD about what processes I have running and what my toolbar looks like in OSX, I don't like the LogMeIn icon always up there.. but that's about the only thing that I don't like.
