It's worth noting that what Kevin stated applies to Netscape plug-ins loaded via the Mac port of WebKit. The Qt port of WebKit uses a different implementation of the Netscape plug-in API than the Mac port. My reading of the Qt NPAPI implementation brings me to a similar conclusion to that which you reached: when NP_NO_CARBON is not defined the code in PluginViewMac.mm will not allow any plug-ins to be loaded. It's also worth noting that there does not appear to be any code in PluginViewMac.mm to deal with the Cocoa event model. This suggests that there is a non-trivial amount of work required in order for it to support plug-ins on 64-bit Mac OS X.
