Oops typo, let me rephrase the first sentence :
+1 to 1) and 3) under the Pipe creation but also 2) , because if one has a
custom impl for a pipe , he probably needs it for each read

Okay for PipeConfig.updateParameterProvider() but he should also be able
to pass anytime through the read() to reconfigure , no ? doesn't hurt to
have many options to reconfigure IMO
Just a last remark on the "locations" name : metadataLocation
and pagingLocation are not enough clear to me to see what's coming in and
out, as suggested on IRC : metadataLocationResponse
and metadataLocationRequest ?
