The practicality of cracking the password is negligible. The passwords have historically been strong enough that unless someone uses a botnet there simply isn't enough time to crack it successfully before Saturday. 0-day hacks into Adobe as attempts to crack encrypted files have simply resulted in 0-day exploits for internet browsers instead of actually unencrypting the files, so I also doubt there are circumvention measures available.

In short: 128-bit SSL is still going strong, so don't get your hopes up of actually reading the contents before Saturday.
