Are there plans to address the currently documented limitations of the iPrint client for MS vista?

Limitations of the iPrint Client 5.x
The iPrint Client v5.x for Windows Vista does not support the following features:

Printer driver profiles
iPrint Client Management
User printers
DOS box printing
Auto-update of the client
Sharing credentials with the Novell Client

Particularly the driver profile one since we want to give our students duplex printing by default.
