Fetching it server-side would allow the server to retrieve a copy only
when it's been updated and then save it in a local format to conserve
unpacking and reformatting time, which I think makes it a better
approach anyway.

Client-side scripting seems to be going through an "overused new toy"
phase. Or maybe that's just my perception, but I get the idea that
everyone feels like they have to keep up with the fanciest client-side
scripting on the block.
