This doesn't really answer the question, unless your position is that any dojo that claims to be doing aikido is doing aikido.
This is a good point and I think there are two things at play, that I can see off the top of my head - not yet having had any coffee (caveat culpa):
1) Where did you get your stuff/transmission, in other words, if you're doing Ueshiba's aikido, what connection do have back to him? Who authorized you to teach? That kind of thing.
2) What are the stated goals for a dojo's practice and how does the training prepare one to meet or exceed those goals?
