Very true.
Layer-2 between sites is evil, as well.
Indeed. Now VmWare actually supports layer3 for vsphere, maybe we will start to see it go away. :)
Layer-3-independence and active/active/etc. is where it's at in terms of high availability in the 21st Century. GSLB, et. al.
Yep.That way all your environments get adequate(ish) funding. Vs management saying "oh it's just backup/dr, we will fund it next year".
