Another interesting aspect in this whole IPRED mess is the amount of time the other ISPs save their IP-address data.

According to the IPRED law it is up to the lower court to order an ISP to turn over the subscriber information, but only after examining the evidence of possible copyright infringement.

This means that if the data is saved for a shorter period than the time it normally takes to investigate an infringement, any order to turn over the data would also eventually fail.

I've heard from at least one ISP that they normally save data for three weeks, so that should be sufficient, unless the courts suddenly decide to start prioritizing these cases. :(
