There is a very challenging document distribution problem in NEOS that this would be a big part of.
The incoming mail problem would be solved by automatically coding the documents as MAIL and associating it to a user.
Any thing with MAIL and a user, would reside on a mail tab. This would now be the electronic equivelant of an inbox. As the user went through his/her mail they could file the mail asd need and set appropriate disries, or just keep it in the inbox to do further work.
This would solve some very time consuming tasks.
