I thought the big time problem wasn’t the dice rolling, but wrangling all the written text in preparation for the dice rolling. [*]
Under that scenario, we want to “farm out” the data entry and regularization, not the actual game mechanics.
To my mind, if we’re going to be sharing spread sheets, a single “input” spread sheet in the cloud (eg a google doc) that is shared by all players and has a clear edit history (to help tack down errors and discourage hanky panky) would be both simpler and more beneficial to the GM.
[*] I got the sense that rolling the dice and watching the battles develop was part of the fun for the GM.
