[c-nsp] IPsec Stateful Failure question

Strange -- we've done stateful IPSec on a VRF interface before.  I wasn't
aware of this supposed restriction.

Subject: [c-nsp] IPsec Stateful Failure question

Before I jump in both feet first and try configuring it, the Stateful
Failure for IPsec guide (12.4) says:

 "A stateful failover crypto map applied to an interface in a VRF instance
 is not supported.  However, VRF-aware IPSEC features are supported when a
 stateful failover crypto map is applied to an interface in the global
 VRF".

If I read this right, then configuring things like this:

interface Port-channel1.106
 description Customer X VPN - Front Door VRF
 mtu 1600
 encapsulation dot1Q 106
 ip vrf forwarding f-CustomerX
 ip address 1.2.3.4 255.255.255.248
 ip mtu 1500
 standby 106 ip 1.2.3.5
 standby 106 follow vpn-vip
 standby 106 name f-customerx-vip
 crypto map CustomerX redundancy f-customerx-vip
end

Means I'm not going to be able to do stateful failover, correct?
