I want to use the desktop 'activities' to perform user tasks automatically when a user creates an activity, ends an activity, switches to an activity and switches out of an activity. I don't see any easy way to do this. Is there a plug in or is one planned?

Some background: my use case is to build a work environment to handle unix systems administrator incident calls in a data center. When the command center calls a sys admin, he is asked to join a bridge line (i.e. Line 4). I want to write a script that accept this bridge line number, then connect to the command center and fetch the incident information. Then I want to use that information to bring up the tools needed, connect to the servers, and log the call in a database. Incidents can stretch over a long period of time so I also want to log time spent on the call based on the time the sys admin is actually in the activity. I'll run a different script to start an activity, to leave an activity, to rejoin an activity and to end an activity.

Activities are perfect for this because they hide everything but the current activity and it is a decent assumption that an active activity means work is being performed on that activity.

This model is not limited to sys admin work. Any business that needs to bill clients based on time worked on an activity could use this model to log time and create customer invoices. (Consultants, accountants, lawyers, programers, graphic designers, etc)

If there is an easy, intuitive, way to capture these four events and allow people to run their own scripts, I think this feature would give "activities" a big boost.
