People can create Projects and repositories. Repositories must have global unique names.

 The project structure looks like that right now

project1_subproject_subproject

project2_subproject

and repository names like

project1_subproject_subproject_repository

project2_subproject_repository

Can the system change,

1. so that people can subprojects to a project?
2. so that people do not have unique names?

I want to create a project structure like

project1/subproject/subproject/repository

project2/subproject/repository

project3/repository
