Here in europe officials deny that their intention ever was to have telcos 
actually record calls and/or internet traffic and save it for 2 years. 
They want to have metadata such as radius login logs, dhcp logs, MTA logs, 
web server logs etc saved for 2 years, not the actual contents of email, 
web traffic etc. They would of course love to have netflow/sflow logs but 
that's going to be a hard sell since a lot of equipment out there do not 
support it.

Some politicians have made statements that might be interpreted that they 
want actual content saved, but when asked I have usually ended upp with 
that it's only metadata that needs to be saved. This is often done 6 
months anyway, so I don't see it as a major hassle to save it 24 months 
instead. The interesting part is the "collission" with the Electronic 
Commerce law in EU that states that data for privacy reasons should never 
be saved longer than absolutely neccessary for billing.

The EU data retention directive is in the implementation phase so we still 
do not know the actual implemented law yet (at least not here in Sweden).
