Yeah, I would shy away from trying to server massive amounts of data thru your webserver - the size of the responses will bog your server down.

Instead - if it's really a -massive- dataset - and you don't need to be serving it up all that fast, you just need to make sure you serve it -all- up when it's requested - how about using email?

It's pretty reliable and can transmit a ton of data without causing any wierd hiccups. It's also fairly easy to write email parsers that can handle the data import too ...
