1password was a weird one for me, I operate on BSD/Linux and very seldomly my Mac (I use an iPhone though) and I wanted to stick with 1password because it allowed me to access my passwords from my phone.
Luckily they use an open specification for the database they use which has a python module[0] and I've started building my own interfaces[1] to interact with the keychain in much cooler ways.
It's no 1password.app though. :(
