Yes -- in a sense, what people also term "generalizing specialist". Someone who may not necessarily be an expert in technology Y, but they can be very effective in it. If I don't know it: I learn it, and fast...and while I'm studying it, and reading every god-awful book / resource I can find on it, I don't charge the client. This is necessary b/c unless you have a dedicated team of people -- each who is good at a respective thing, you -- as a consultant, will just be expected to get it done...quickly, and with high quality. You can do consulting in your own comfort niche. I choose not to do that.
