yes, but once its open, it's open. and people are highly likely to open the archive, and keep the document unencrypted on their laptops.
here some form of document DRM could be a quite workable solution. I've been using Microsoft RMS as work as part of a pilot and while it has a few gotcha's, and while it does sometimes seem that MS just don't "get" how people use their software, it does seem to work.
the documents are encrypted within office apps (word, excel, outlook and powerpoint) and it has to authenticate itself to the RMS servers to get the keys.
