Following on from this topic: http://forum.virtuemart.net/index.php?topic=2079.0
I have created a new Sage Pay VSP Form payment module which uses the new 2.23 protocol.
Extra fields have now been added to transfer billing and shipping address details.
May be someone can modify it to work with Virtumart 1.1.x!

All I get is Direct Access to this location is not allowed when I try and save the new payment method?
