What interoperability issues with keying? IKE which is pretty much universal is built on a standardized framework - ISAKMP which specifies how the key exchange mechanics work. IKE is made up of 3 mature and standardized protocols - ISAKMP, OAKLEY(which modes) and SKEME(for pub key-based exchanges). In a past life I configured VPNs, often between sites where there were disparate vendors on both ends. Never once did I run into an issue where a VPN just wasn't possible because of interoperability issue.
