Hi, So system.multicall is implemented in CVS as well. See http://www.xmlrpc.com/discuss/msgReader$1208 for the spec. I multi-called some methods from Python and it looked ok (both normal return values and faults "looked the same" as the examples in the spec). I introduced a literal string so the fault structures can be stuffed in the result array without being turned into strings with xml in them. Now all of the xml-rpc extensions I know of are implemented; if there's another one I'll likely move the lot into their own file so they don't clutter up the main server code. Cheers, Rudi
