Can anyone confirm this? (Michael was not sure).  If it is true then all
sorts of interesting things become possible.  For example an application
could push a compression module to automatically compress it's disk
files and other applications could access the data by pushing the same
module.  Other possibilities include an encryption module, EBCDIC
module, etc.
