I agree with letting the interview know you are interested in their company. Inquisitiveness is a key character trait we look for and asking intelligent follow up questions is a great sign rather than someone that has just thought of a list of pre-canned questions beforehand and is going down them.

But I wouldn't view letting on about other interviews a major problem -- knowing there is some competition both ways isn't a bad thing. I want great candidates to work for us, but I also know great candidates have choices.
