Yep, I think we all accept that there will be some "degradation" in terms 
of the actual "line rate" that would be observed.
I'd venture to suggest that so long as the performance is "better" than 
doing it across the network and on the origin server then you're OK.  After 
all, we know that caching proxies degrade performance for cache misses - 
the key is how much they can enhance performance for cache hits.
