Seems like a solid proposal. I'm not familiar enough with the  
extension mechanism to know if you need some extra stuff to define the  
extension URI and so, but the idea seems solid.

One comment, it will be difficult for the plugin to know when it can  
clean up the file. Obviously on UNIXy systems you can unlink it after  
returning the FILE * to the host, and let the filesystem garbage  
collect it later, but I don't think you can do that on Windows.

Maybe it would be a good idea to provide a lv2_dyn_manifest_done()  
function or similar, so that windows-based plugins can clean up their  
temporary files?
