I do. As of right now I've got an 1721 + 1841 and two Redhat servers at home
which I can possibly test with (and I'm interested in getting WCCPv2 support to
work with squid as a bit of a hobby).

I've had big issues with a simple WCCPv1 setup in recent 12.4 code though and
even bigger problems getting Cisco to admit it and fix it, although it does seem
to be ok in the very latest releases (12.4(7) and 12.4(6)T). So be careful
you're not testing against code which you aren't 100% certain works otherwise
you'll waste a lot of time :( That aspect I can probably help with.

I also have an old and now EOL Cisco Cache Engine 500 gathering dust if you want
to see some WCCPv2 in action and watch how it works.

I was told in a Cisco WAFS course last week (which is in itself an interesting
CIFS cache system that uses WCCPv2) that this hardware based L2 forwarding only
works on the 6500 switches which means it's really for the high end of town.
Everything else needs to use the GRE tunnel method.

If you'd like me to test please give me some detailed directions on exactly how
I need to set it up and configure it and what to look for and ignore, and I'll
give it a go. I know how to apply a patch, but I guess there's some Makefile
editing to do which is where I'd become unstuck without a bit of guidance...
