It would be great to be able to have developers control the hooks used by a repository. For example, using the pre-commit hook to require a comment on every commit.

Sublime will install and manage Apache allowing for HTTP access of SVN repositories and windows authentication.

Currently the LDAP auth does not cater for sub-projects. It is possible but this requires admin outside of Sublime, which, of course, is not the point

Ties in with the incremental backup request but allows multiple full backups to be stored - basically implement a retention policy

Allow users to view source code, blame, diff and other views from the web interface.

Allow repositories to be owned and managed by more than one user - or even a group. This would allow multiple people to assign permissions and edit repository settings.

Separate the Sublime web interface from the subversion server and allow Sublime to span multiple SVN servers.

Tie SVN repositories to SharePoint team collaboration sites. That way documents and project info could be in the SharePoint site, and code could be in SVN.

Provide support for incremental backup as well as full backup.

Support authenticating via SSPI

Users should be able to specify whether or not they want to receive email notifications.

Reporting tools for viewing permissions across repositories. View permissions for a single user or group etc.
