If you're sympathetic to libertarian ideas, I'm surprised you're not interested in furthering discussion about libertarian approaches to spectrum allocation and land use and transportation policy. What mainstream websites/blogs/pundits do you know of who give anything more than a passing mention of these issues? I find that these issues in particular (IP not so much) are woefully neglected by...just about everyone. Even libertarian organizations (Reason magazine and foundation come to mind) often have very statist stances when it comes to land use and spectrum regulation.
