Has anyone tried to Archive Old data (messages)?

I have a fairly active board and in order to keep the speed up and storage down, I was thinking of archiving old data. The ultimate setup would be to have that data usuable from a remote location. For example I Archive to a CD and send it to members, then they can use the CD to browse history.

Any ideas?

Don't have a clue as to where to start.... that would be very cool though.

A couple years back I did this with Acrobat on a different message board script.

Worked well because all the links worked in Acrobat, so you could move from post to post.
