Can I Run WCCP Across the WAN to an External Squid Proxy

In all my experiences using WCCP redirection (mostly with respect to WAN Optimization devices), I've always done the redirect to an internal device (behind the firewall). Can WCCP be run across a Wide Area in order to redirect traffic to an externally hosted Proxy server? IT would have to be forwarding via GRE. Any advice would be greatly appreciated.

Yes you could.  First thought is that sounds a bit slow.  What is the bandwidth and latency over the WAN.  Sounds like you are going to be adding a bit a latency for users trynig to access x, assume Internet sites.

Well, seeing how this proxy is really part of a bigger cloud/SaaS security solution, latency is not really as much as a factor as just being able to redirect the traffic via WCCP to the cloud. There are other options, like GRE with pbr, but in this case, I'm dealing with a dynmaic IP address on the remote side...so a GRE tunnel will not really work for me.
I will step back then, as I only see that you can redirect WCCP to a specific address.  If the address is dynamic I would not know how to do this.

Actually you can run WCCP as a multicast group.  The external hosted proxy server would just have to join the multicast group.
Is this resolved.

This is resolved...I'm going to go with L2TP tunnels rather than WCCP/GRE to redirect traffic
