I am looking for a JomSocial addon - that works like this:

Background:

Website: It is a sports community where people of all different sports interact and find training partners.
The Addon: The addon must work similar to a "Poke" system, but obviously alot more advanced.

Job Specification:

We are looking for a addon that will let users "Challenge" each other at certain sports. If a user challenges another, it must display a notification to the user who was challenged that there is a pending challenge request. Similar to JomSocial private messaging in a sense. The challenges must display in the JomSocial activity stream and include the following:

"X challenged Y at {sport}!"
"Y accepted X's challenge at {sport}!"
"X turned down a challenge request from Y"

Notifications must be sent every time an action is made. If someone denies the challenge request, a notification must be sent to the person who placed the challenge.

Once the challenge has been completed, they can enter in a result and then the activity output looks like so:

"X beat Y at a game of golf"

Inside the JomSocial profile of the user, it must keep a record of this. So in my "Challenges" application on the users profile, it will show past challenge results:

"X beat Y at a game of golf"
"X beat T at a game of golf"
"X lost a game of golf to B"

More Information:

In the "Create a challenge" popup, it must include a dropdown box of sports and a textbox for a brief message.

It must be very easy, visible and fun to use.

Notifications of each action and output into recent activity is key.
