To start with "Public" is a bit of a misnomer, you can think of it
more as "Shared". The goal is just that if you have a place you can
put the tools, rather than
a) Downloading them from ec2
b) Having to upload them to each User's private space.

Arguably for many cases for MaaS (a) should be explicitly blocked by
the firewall.

For MaaS I don't know if there is an idea of many user accounts, so
there may only be the shared space.


As for findMongo(), if the documentation says it can return nil, then
we just need to teach findMongo about what to do if it gets nil
(return immediately). [aka just a bug]
