In my solution I do store the buffer. Maybe for some reason the id is in another buffer with narrowing, and you want to preserve that narrowing when you return. I originally did that with a marker, so you could restore point to, but I decided to take that out. I wasn't aware you could have dangling markers! I guess you would want to use more global variables, so there would only be two. and hopefully you don't follow multiple id links through narrowed buffers in a row!
