So my take on this is currently: 1) Implement org.jboss.virtual.plugins.context.memory. MemoryContextFactory MemoryContext MemoryContextHandler 2) Plug the context factory for vfsmemory into VFSContextFactoryLocator 3) VFSTopLevelClassLoaderSystemDeployer a) When creating the top level classloader pass in a memory virtual file as one of the roots b) Attach the memory virtual file to the deployment? 4) AspectDeployer a) Get the memory virtual file from the deployment and output the generated classes to there (possibly using the AssembledXXX stuff?)
