[Zope] XMLRPC:XML Compressors - anybody experienced it?

Since XML blows lots of overhead over the line sending large amounts of data via XML becomes a performance question. There exist XML-compressors, for example XMill that address this problem. What I need is integrating such an XML compressor into the Zope XMLRPC mechanism, Before I do something that is already done by somebody else: Did anybody play with XML compressors for Zope or at least have a hint how to do that? thanks
