Alexander,

I haven't worked with WAAS 5 yet, but I did earlier versions of WAAS, as
well as multiple versions of Riverbed as well as the Citrix accelerators.
 I always refer back to the Gartner report, and my own RFPs have borne out
the same results.

I'm not a fan of WCCP... it is a 4 letter word. My biggest problem is that
you have to be really careful on the platforms you choose. I found that
some "router" platforms switch from hardware switching to software
switching in the presence of WCCP, and like the Cisco 6500, they can't
handle it. Other platforms might not have such a hard time.

Travis,
You have to be careful with generalizations. I've found that COTS SQL can
actually do well, but many home grown apps are a problem. But, yes, FTP
and CIFS can have significant improvements.
