Another option I would like to see is to be able to use multiple git 
repos within the tree. This could then be combined with symlinks: e.g.

.password_store/secrets -> /home/me/secrets
.password_store/customer1 -> /home/me/customers/one/password_store

Then you could do:

pass show secrets/production/database_password

as if it were were a single pass tree (but actually commits would take 
place within secrets/.git)

Brian.
