That's a problem with the end-point, not with the medium. Consider a system like RT[0]; it has no concept of an inbox, yet most (if not all) client interaction

That's a problem with the end-point, not with the medium. Consider a system like RT[0]; it has no concept of an inbox, yet most (if not all) client interaction is via email. My take is that if you're tempted to set up a shared inbox, don't. Set up a ticketing system instead. [0]: http://bestpractical.com/rt/ http://bestpractical.com/rt/
