The free version can be used on multisites: Their limited features has no effects on this.
With the PRO-Version you can store Templates in the database for using it on multiple pages / blogentries. As these Templates are stored site by site multisite Management comes into the game. PRO-Versions prior to 2.0.9 do not support multisite. Versions after 2.0.9 are multisite ready.

Thanks to Rod from Canada and Layth from Australia!
