Response was overwhelming, and I've finally gone through all the responses. Requests for summary were overwhelming, and I've BCCd all of those who requested that, but thought I'd CC the list since there's such interest. Thanks for all the feedback, especially those who took the time to provide official responses from the various corporations... and I'm sorry I couldn't respond to everyone individually. Ehud LSRR and SSRR SUMMARY: Some providers REQUIRE it for peering. Lots of providers ALLOW it from customers and peers. Only one was verified to deny LSRR/SSRR and admit to it.
