ams-ix - worth using?

(I know little about AMS-IX and am still waiting for someone from there to get back to me...) My NA bandwidth right now is ~200Mbps and about half of that appears to be EU destined. I'm opening an EU POP soon and am trying to figure out what sort of value AMS-IX would give me. Does it simply provide an easy way to privately connect to transit and peers? Or can I also go crazy and peer with anyone who wants to peer (like in the olden day!) ?
