Adding post form to a friends profile - allow you to post on their wall

I love Activity Plus - if i had to name one plugin that i have found ESSENTIAL to BP it is this plugin...

I always try to stay current and came across the buddypress wall plugin

My BP and Activity Plus does just about all this plugin does BUT I MUST ADMIT - the ability to write on a FRIENDS's wall is fantastic... see attached pic

Surely we can "tweak" Activity Plus to do the same?
