    User can access Pirate Drive as U: drive using desktop application
    Reservation for Linux
    User can mount Pirate Drive into their current file system
  • Apache VCL File Submission
    Send files as e-mail attachments
    Set Pirate Drive permissions to allow faculty to view files
    Use faculty designated persistent storage
    Use reserved computer’s web browser to upload to Blackboard / Moodle
    **New for ICTN4800, Fall 2010- student-initiated automated grading and feedback!

    Web plugin allows access to local computer storage (if user desires)
    Web plugin allows access to local printers
  • Citrix VCL Features
    Because Citrix VCL servers are trusted ECU machines, students can access network resources not otherwise available
