Pretty interesting that you use "1password (PeopleOps vault)". I guess I never thought about using PW-vaults in a corporate setting. Seems like an interesting approach (compared to some alternatives I know that don't work well).
We're using 1Password for teams at MM.LaFleur and it really is nice. A lot of our employees were already 1Password personal users, and the Teams for 1P just started in Beta when we started looking for a new way to share passwords in a corporate setting, and after trying some different options out this was by far the best.
You can add people to specific vaults and it works really well.
Especially considering there is no native Linux client. They say that's explicitly why your choice for development machine is one of the following: 1) Macbook.
