I am looking at a project that will require a user based process to interact with the system as if it were a filesystem. The traditional way I have seen this done is as the system NFS mounting itself (ala AMD). I would really like a more clean approach to this. What I am interested in is a 'User Space File System' that would interact with a user process in a similiar manor to how nfsd's do. A process would issue a mount (ok, this is different than NFSDs), then it would make a special system call with a structure, that call would return whenever a request was pending with the structure filled in with the appropriate information. The user process would fulfill the request, pack the return data into the structure and call kernel again.
I have a number of questions on more specific ideas (like caching, inode/vnode interaction, etc). But I am just feeling arround for what people think about this.
