Hi lads!

I'm XO's project leader

• @scottalanmiller XO does provide DR features, see https://xen-orchestra.com/docs/disaster_recovery.html
• @johnhooks it's all Open Source (aGPLv3). If you don't want the turnkey solution (appliance and pro support), "use the sources Luke"
• about the price itself, please consider you'll have an appliance with support working out of the box (plus the web updater). And price is flat.
• complete features list is here: https://xen-orchestra.com/docs/features.html

Last thing, about using it inside or outside your infrastructure: because it's agent-less, you can use it everywhere. You can even imagine a small host with only XOA inside, the thing needed to "talk" to your others XenServer host is only a TCP connection to port 443. VPN connection to multiple datacenter is fairly possible (or other tunnels).
