More Than 5 Computers Authorized Possible?

I know Apple limits iTunes authorization to 5 computers, is there any possibility trying to get Apple to bump that up? My family of 4 has 6 computers (4 iMacs, 1 MBP, and 1 MBA). Right now I have my daughters iMac deauthorized when I got the wife's MBA, but want to get her iTunes music library synced up. We share playlists from my worship teams weekly playlist and it would be nice to have MusicMatch enabled on all 6.
I imagine this isn't possible, but wanted to see if anyone has ever tried successfully to get this done. I mean we have over 16K in Apple products, would be nice to have the family share music and app library.

 

Yeah I was expecting as much. But sure would be nice if they would. Maybe make sure their all on same subnet / location. Sure many apple families are like ours.

Guess I shouldn't buy so many Macs.
