Thanks Ola!
I think this should work fine with nsvhr/nsunix as long as the XML-RPC client that you use sends an appropriate Host: header. This was a problem with the client inside ns_xmlrpc, since it used util_httppost to POST requests and util_httppost doesn't send Host: headers. So, I rolled my own HTTP POST method (well, stole it from lars-blogger). I should probably fix util_httppost too...
