sorry the late reply matt. i saw this post the day you wrote it but forgot to reply. oops!
anyway, it's a great idea and one i had thought of when first thinking of implementing the spreadsheet. in fact, i would like to have a lot more excel-like functionality built in like the ability to sort and mix and match columns. exporting the data should not be difficult.
i just need to get a little development money for tasking the programmers with this project as it is quite a feat to make it all work. the spreadsheet component uses flash graphics and a programming language called ajax (i think, maybe i'm not remembering correctly).
anyway, expect this and more come next year.
