BuddyPress.org

i am developin this web application and buddypress framework seems to go about it reasonably well, now i want sumone to help me out with sum codes or some form of plugin that can notify users when a group or some specific words i assign to it are menthioned

for example… i create some groups say {yahoo, google, buddypress, facebook}

i want a situation whr, when sumone in facebook group mentions yahoo or anything close to yahoo or google or buddypress, i want members of those group to be notified and can be sent back to thr groups via email or anything
