How do you know whether the data source is overloaded or physically more
distant?  Freenet's way of distributing load might not be optimal in all
cases, but deliberately concentrating load seems like a poor alternative.

How do you keep spammers from using automatically generated requests for the
same effect at even greater cost (with or without redirects), or inserting
tons of their garbage to push everything else out of everyone's cache and/or
clog up the network?  Hit-count updates would only have as much credence or
effect as the recipient is willing to give them based on authentication,
past history, etc.  If it smells funny, drop it.  After all, it was only a
hint so, by definition, dropping it won't break anything.  Dropping
redirected requests would be much more disruptive.
