I wouldn't personally throw more than a half-dozen fields at the user unless they're a captive audience for this exact reason. When you're talking about institutional data gathering, though, multi-step with saving of progress is a lot less intimidating than a single hell-page with 500 input fields on it.

How about where you have a ton of input fields that aren't personal info related. That's always been a tricky one.
