Can you actually write to the /proc directory? Working with libfuse I've had much of the same ideas, basically allow programs to expose information as files. The beauty of the fuse system is also that you only have to respond to requests when they happen. So you don't have to actually create all these files until someone asks for them. Another idea I've had is to expose the configuration of a program through a filesystem. Instead of having a config file and a refresh command or a complicated IPC you could simply write to files to change the config.
