Joe, this is a great question, in order to gain some visibility you may consider moving it to Internal Community Managers where there are lots of people with first-hand experience. If you are looking for an Austrialian perspective, I think you have it in the right place, but should consider cross-posting (creating another post in the other group linking to this one) to gain visibility. Just some tips on how to get the best response. Definitely let us know how we can help. =)
My 2 cents, whether en masse or trial, the implementation becomes an en masse implementation as the solution goes viral. This is a very common theme in most of our customer case studies.
Hope anecdote helps. =)
