Dropbox

Project Status

Jason will do presentation at the August 6th weekly meeting.

Questions and Concerns

• What is the maximum file size supported for transfer?
• Is there an issue when large numbers of files must be kept up with?
• Do we want a Dropbox style service or an FTP style service?
• How well does the solution handle file permissions, especially group permissions?
• Do we want to survey the users to see what features are most important to them?
• How much service level maintenance or intervention does the service require?
