Presence module wanted...

Hi!
I was looking at the trixbox forums a while ago for a presence appplication but this might be a more appropriate place for this? Has someone thought of a presence module to let the end user set their presence information by phone/ARI? I'm missing this important feature. It would be something like this:

- Call *23 (or whatever) get a prompt to enter reason for absence.
- A list is provided
0 lunch (default 1 hour)
1 meeting
2 gone for the day (default back 8:00AM following day, OR monday if set on a friday)
3 sick
4 with sick child
5 temporarily unavailable
6 vacation
7 leave of abscence
8 whatever
9 whatever
- calling *23 not providing any options would present the list
- calling *210 would set the presence to " out to lunch will be back at (whatever time occurs after 1 hour)".
- calling *2101330 would set the presence to "out to lunch, will return at 1:30PM"
- calling *2111530 would set the presence to " in a meeting, will be back at 3:30PM"
- calling *2162006 would set the presence to " on vacation, will be back on June 20th 8:00AM"

You get the hang of it now I guess?
This is heavily used in Europe and maybe mostly in Scandinavia in any phone system and is a key selling point for phone systems here. TB/FreePBX, not saying they are the same, lack this feature, and I think the best way to implement this is through FreePBX/PBXmanager. I would very much like to see this module created. I don't think it will be rocket science to put together either. But my programming skills don't amount to much so I ask you if this is doable for TB? OR if something like it already is in the making? Haven't seen anything about it though?
Would there be enough intrest for this to have it developed?
Kindly
