WCCP Router config

Question

I found this paragraph in the IOS 12.x documentation. The second sentence seems odd to me. Because WCCP redirection was enabled on a specific interface, it affects all interfaces on a router. Does it only affect interfaces that have an outbound redirection statement associated with them or does it affect all traffic on all interfaces?
Configuring WCCP for redirection for inbound traffic on interfaces allows you to avoid the overhead associated with CEF forwarding for outbound traffic. Setting an output feature on any interface results in the slower switching path of the feature being taken by all packets arriving at all interfaces. Setting an input feature on an interface results in only those packets arriving at that interface taking the configured feature path; packets arriving at other interfaces will use the faster default path. Configuring WCCP for inbound traffic also allows packets to be classified before the routing table lookup, which translates into faster redirection of packets.

Has anyone tried configuring a Cisco 2621 with NAT/CBAC/CEF/WCCP simultaneously? I have a branch office connection with a single router and am having serious trouble getting CBAC and WCCP to work nicely together. I'm redirecting to a Volera Cache Engine. Synopsis of config:
