Thanks, Eric, for bringing this up for discussion. I think this is a conversation that many of my colleagues (bio/statisticians in schools of medicine) have on a weekly basis.
First, I want to comment on the distinction between consulting and collaboration. I think your definitions are spot on, especially as they relate to the amount of time, energy, and investment a statistician may put into a particular project. And I think many (if not most) in our profession are clear on the differences between consulting and collaboration.
However, the problem lies in the perception of consulting/collaboration by our non-statistical colleagues/investigators. I don't want to paint with a broad brush (since I have many collaborators who are fantastic), but I think many investigators view what we do solely as consulting when in fact it should be collaboration. This includes, but is not limited to, last-minute power calculations on grant proposals, not including the statistician on any project-related conversations until it's too late (i.e. year 5 of the grant), etc.
Furthermore, there are many investigators who truly want to collaborate with statisticians, but their expectations of what "collaboration" means falls short. For example, their assumption is that for a little bit of effort (i.e 5%), they will have a PhD level statistician who will do all of the data management, statistical programming & analysis, and writing of papers. While this is true to some degree, none of this can be done well alone and without high-quality statistical and data management staff (bachelors/masters level who also come at a well-justified cost). This is even more vital in clinical trials.
As a statistical community, we have to continually make sure we're advancing our profession forward. Not only do we have to make the case to our colleagues/investigators that collaboration (versus consultation) is vital to the success of their research projects, but we also have to make the case that it's vital to the success of our careers. Namely those of us in academia.
Thanks again, Eric, for stimulating discussion on this.

Subject: Consulting v. Collaboration?
Dear ASA Community:
What do you think is the difference between statistical consulting and statistical collaboration? Also, is the difference meaningful, and if so, in what ways? (And what is your reaction to my answers below?)
In the hopes of stimulating some discussion, here's what I think...
The distinction I make is that statistical consulting is helping a client (colleague, boss, anyone...) answer a statistics question, and statistical collaboration is helping a client (anyone...) answer a research or business question.
I think the difference is meaningful because, if a statistician focuses on collaboration (to answer the research or business or policy question), he or she will add much more value to the client/project/company and achieve greater impact than if he or she just answered the client's statistics question. Furthermore, focusing on the research/business goals will help the statistician figure out what the appropriate statistics questions are. If you've ever done statistical consulting or collaboration you will be familiar with the concept (defined in 1957 in JASA by A.W. Kimball) of the Type III error--giving the "right" answer to the wrong question. My experience running LISA at Virginia Tech is that focusing on helping the client answer their research questions rather than just their statistics questions leads to much better outcomes for all (better experience for my statistics students, better answers for the clients, and better appreciation for the extraordinary power of statistical collaboration to solve problems).
Furthermore, "collaboration" is valued much more highly than "consulting" in academia. It's a challenge to promote or tenure a statistician for their consulting work, but collaboration is more valued now with the rise of interdisciplinarity and team science. Sharp et al. provide details about the perceived value of statistical consulting in their recent paper
