You would either need a JavaScript library (which doesn't exist yet) or you would need to convince browser vendors to support lepton files natively.
In Dropbox's case they control both client and server and can just compress/decompress in the dropbox client. Using lepton on websites wasn't really Dropbox's goal (but it would be cool if a sufficiently fast JavaScript library existed).
