* Appending to a read-only filesystem on a separate volume
* File versioning
* Transparent, variable compression
* Format conversion, (I.E. write a png file to a filesystem, and it is
automatically visible as half a dozen other

write-cache, instead of flushing them along with
other more-important-to-get-to-the-oxide data)
* WORM mode, (I.E. start at block 1 and use blocks sequentially, never
re-using blocks - makes a tape somewhat usable as a
