Feature for forum - personal away message on hover

Pretty self explainatory there but I thought that it would be a nice feature to let others know " I appreciate your feedback on my post and will respond asap " or " I'm active on WPMUDEV daily and look forward to responding to comments " or " I'm on vacation but will return in a few weeks " ...

Why - the community is priceless and sometimes I feel like I've left people hanging. By having a status of sorts just gives me the peace of mind that I've let those interested know that I'm active.

Just an idea : )
Hope that you guys/gals have a great week.
Cheers
Jason
