"DOJ Seeks Mandatory Data Retention Requirements for ISPs" - I don't why this is news to Computerworld. It's already far too late for that, it's already case law.
ISPs should already know this and the fines they are going to get if they don't keep those logs.
Information is recorded, however briefly, in RAM and should be kept. In 2007, TorrentSpy was sued by the MPAA and the court ordered them to turn over the server logs. TorrentSpy said they didn't keep them, the court said they were already in RAM and they should have - effectively accusing them of destroying evidence and they were fined $110 million.
F100 Bank: Failed to furnish records – much of which was log data, resulting in $10m civil penalty
J. P. Morgan Securities, Inc. – failure to have adequate email preservation systems or procedures resulted in a $2,100,000 settlement and consent to establish procedures
Prudential Ins. Co. Sales Practices Litig. $1,000,000 fine by the court was imposed for document destruction

The idea being the information was already in computer RAM and should have been kept. The last one (Prudential) is interesting as by not keeping a record of what was in RAM then that could count as document destruction - but I think their case was more to do with actually deleting documents.
Here's a case involving a music sharing site - http://www.mcbride-law.com/2009/12/22/production-of-internet-server-log-files/
The judge found against the site because
a) RAM is fixed for a short duration and the log files should have been kept.
b) Even though the actual servers were not owned by the people doing the file sharing they should have kept the logs in a).
c) Because of a) it required no extra effort to produce the log files as they were already in RAM and technically already in their possession.
d) Even though the servers were in the Netherlands the defendants (in the US) had control of those logs and should have produced them.
All of which may have some serious consequencess for the users of Limewire, maybe Bearshare and Frostwire as well if they end up in court as well, as those server logs contain the IPs of everyone who used them and the RIAA may well come after the major downloaders of those files.
Laws like SOPA won't get passed because it is too wide ranging but ISPs and the content providers have had pretty much a free rein over the last 15 years and can't or won't police themselves so now the government is going to force them to. It's nothing new, the pharmaceutical companies didn't either now they've got the FDA. Banks couldn't now they've got the SEC and about another zillion bodies watching what they do.
