Microsoft CARP

I just reed the Cache Array Routing Protocol (
http://www.microsoft.com/proxy/guide/CarpWP.asp?A=2&B=3 ) and they say
that CARP is better than ICP because:
1.-ICP queries produce congestion. CARP use a deterministic request
resolution path.
2.-ICP servers 'can rapidly evolve into essentially duplicates caches of
the most frecuently requested URLs'.

What I think is that MS does not understand quite well ICP:
1.- ICP are short UDP (conexionless) packets, also you can use
multicast. In my case (I'm a ISP in Peru, and the link to USA is bad:
600ms minimun delay, 10% packet loss) ICP respond rapidly in changes in
lines conditions. I dont understand quite well how deterministic request
resolution path works, but I don't think that is as dynamic as ICP.
2.- If you dont want duplicates caches URLs you can use PROXY-ONLY
parameter.

Any other opinion?
