Export/import, defaults, or mirroring on WPMS?

I’m running a WordPress Multisite network and need to implement Shareaholic across twelve sites, at the top and bottom of posts. That means a total of 24 separate setups (unless I dare also add Sharaholic to some pages).

Is there any faster way to do this, like setting a network-wide preference, exporting and importing settings, or setting defaults so I at least don’t have to customize the buttons twice for above and below content?
