Thanks to our study of similar solutions, we know that the DueProps concept works on a departmental (or divisional) level, or at companies that are small enough that everyone knows each other. The theoretical maximum desirable user count is probably similar to Dunbar's number, around 150 people. You can’t roll out a single monolithic due props network instance across thousands of people in an enterprise because the activity streams would be mostly filled with meaningless content. You'd be forced to implement Twitter-like functionality to cut it down to a manageable list of people that you "follow."
DueProps currently contains a hastily-implemented, lightweight, implementation of "followers/following" functions precisely because our biggest pilot customer brought aboard close to 200 people in a short timeframe and generated so much content that it was impossible to keep up with adequately.
Upvoting (a.k.a. "liking" a particular instance of given props) can especially only be done to the extent that you know someone and you’re able to make a value judgment as to whether what they did is something that you agree they should get props for. I would think that it doesn't make sense to upvote random props where you have no idea of the context in which they were given.
It's clear to us, from a product design standpoint, that we need to facilitate the creation and affiliation of small (10-50 people) loosely-coupled networks of DueProps users under the umbrella of a larger organization, whether that's a big Corporation or volunteer group, or university, or whatever makes sense.
Beyond the UX mechanics of facilitating the creation and affiliation of networks, we also need to keep in mind the kind of reporting tools that we provide. Some of them will be extraordinarily valuable across larger enterprises. We also should probably be more flexible about allowing different groups to integrate and having different bonus budgets for different groups as opposed to a single company that in most cases, won't have an overarching bonus pool. (It could definitely have specific sets of prizes for individuals winning the most props overall, or most of a certain type. We've imagined things like the top winner of Speed Demon props for the year would get a Ferrari rental for a week.)
