I think I read something about it, but I did not look into it in detail 
so far.

Great! And do you think that using URLs makes sense? An extensible 
mechanism would certainly allow for crazy things: Use HTTP URLs to 
access rrdfiles over HTTP by first downloading them - not that it would 
be very efficient, but...

And just to write it down for better reference: The proposed scheme is 
intended to allow to use different rrdcached connections in one 
invocation without resorting to environment variables.

Would it make sense to split responsibility for implementing this, so 
that I do not trample on somebody elses code? Also note that I do not 
have any code so far,  so there won't be patches by tomorrow...
