Need multiple-entry form ideas

Part of the project I’m working on is going to require the user to create up to eight sections that take similar data. i.e., section name, unique addresses, etc. I’m trying to come up with a graceful, quick way that this can happen, perhaps in a single-page tabbed environment, that won’t require the time and expense of a page load for each entry, but I’m drawing blanks both in my head and in the forums. Some sort of ajax solution? Unordered lists? Something else? My concern is that they will get through two or three, get tired of watching each page load, and dump the process entirely. Which is, of course, bad for business. What has anyone out there done in a situation like this?
