Notes on Messaging for workshop

General observations

• Frequent limit on attachment size
• Mailbox quotas
• Very frequent limit on attachment type

IFolder: P2P file sharing (http://usefulinc.com/edd/blog/2004/8/28#18:41)

• Create an iFolder
• Send an invitation email out -- iFolder "consumes" this email and reacts to the invitation
• Problem #1: Difficult to configure iFolder to send the email - it wants to use your SMTP server directly
• Problem #2: Not integrated with instant messaging.

Xythos: WebDAV file sharing with email "Intellittach" (http://www.sharemation.com)

• Each user sharing files must have quota on a server
• Can upload file and then send out email through WebUI^?
• Can subscribe to get email notifications when file events happen
• Outlook plugin for "Intellittach":
  • Replaces standard attachment semantics
  • Uploads "attached" file to server and gets URL for exclusive use of recipient
  • Puts URL in email and sends
• Benefit #1: Administrators like removing big attachments from mail server
• Benefit #2: Users can update files in-place on server rather than send updates via email
• Problem #1: Requires Outlook plugin
• Problem #2: Client doesn't know well enough to synchronize attachment if it wants to view offline

Chandler

• Early proposal: Share/synchronize everything via email
• Next approach: Share/synchronize everything via XMPP
  • XMPP "compared to" SSL page
  • Note what this means: Messaging is considered a transport
  • Implications for messaging scaling -- success breeds disaster
• WebDAV sharing similar to Xythos
  • Invitations via email currently
• Single item sharing via email
  • If recipient is Chandler, Chandler updates existing shared item rather than two separate copies
