Hmm, I was thinking about doing something similar to what OpenDocument
does by storing a mimetype file uncompressed on the root of the archive.

In this way we can sniff the mime type while retaining full
compatibility with zip files. Also, we can sniff for different kinds of
bundles, if we reserve vnd.olpc-sugar for activity bundles.
