The Mudcat database is VERY portable. Doesn't really take up too much disc space at all.The way things are, they COULD perhaps make it even easier to duplicate since the Mudcat is already in A database for the online version, you could almost make it platform independent if the same database system is usable on Linux and Macs which might be possible.
Again that wouldn't take up too much space even then. Considering a CD-R is about 700M, you have tons of room. And the smallest Hard Drive is probably in the order of 20Gs. Very doable.
Question is how easy would it be to change over from the current system to the online one for downloading?
Not that I am suggesting that Pene or Joe or Dick, et al DO this. Just musing and perambulating through my tiny mind.
