What are y'all doing for CALEA compliance?

What are you RENs out there doing for CALEA compliance? Is there actually any teeth to the law? Our systems guys have tried a product called 'Open CALEA' but the router and the server simply can't keep up with mirroring from a 10Gbps connection into a 1Gbps link. I'm no legal expert either....any lawyers on this list? Thanks for all the great advice. This is a great community! -ben
