Very nice. What about adding this to the curl extension using PCS ? Actually, one of the objectives of PCS is to allow adding an OO layer above function-only extensions without having to write it in C. I cannot dream of a better use case. Less than one hour of work to integrate it. If you send me your scripts, I'd be glad to build a POC.
