E.g. making your unix $HOME/.plan a named pipe to give a different message each time someone finger's your account; delivering location- or browser- specific content from the same url. @Matt It might be handy to define an extended attribute to contain the md5 checksum of the file, though you need to either update this on each write (ugh) or re-compute at regular intervals (ugh). An encrypted version of the file will require approximately duplicate space. Filesystems/storage are beginning to handle checksums/encryption internally; how about an open(2) that allowed access to that info (yeah, very problematic).

Holographic storage is a natural fit, plus you may end up being able to do amazing things. Imagine getting the md5 checksum of a file without having to compute it on the fly. It would just be a property of the file. Want an encrypted version? No need to do the work, it's all another property of the file. Hopefully the real world works like my dreams ;-) I’ve thought about things like this as well. Holographic storage is a natural fit, plus you may end up being able to do amazing things.
