google, and yahoo? Are there laws against limiting the scope of your service that the rest of us should be made aware of so we don't accidentally run afoul of them?

Also, how does trying this in a California court jive with the 11th amendment?

I'm talking about http://torrentfreak.com/u-s-government-seizes-bittorrent-search-engine-domain-and-more-101126/

Thanks in advance.
Also, any opinions on how this affects safe harbors and DMCA would be appreciated.
11th amendment refers to the U.S. constitution
