Not Client Duplicator. Why make add Client Duplorcator?
I think you should read up on the use of "not" versus "no" and "none" and "not any" along with the parts of the sentences they can be used with and the additional helping words that are required to be syntactically accurate. I notice that is one of your biggest consistent mistakes and impedes understanding considerably more than other mistakes.
If your intended meaning is "Instead of Client_Duplicator, why not make a Client_Duplorcator?" then my answer is that the additional functionality of the duplorcator over the duplicator is primarily server sided rendering tricks, which cannot possibly be emulated from the client side. If you mean to say that there is no Client Duplicator/Duplorcator, then yes there is and it is included with BuildBot.
