Just for the record on the list, there was up until recently a great page that showed how to use the rlm_raw module here: http://sourceforge.net/apps/trac/hotcakes/wiki/YfiTechDynamicClients But unfortunately this page has been moved/gone. :-( After a bit of digging I found the original page cached on the 'wayback machine' here: http://web.archive.org/web/20131203083354/http://sourceforge.net/apps/trac/h otcakes/wiki/YfiTechDynamicClients Unfortunately the images are missing though. Just putting it here if anyone else wants this page in the future... Cheers Kev/.
