Do you really mean "jailed", or are you talking about the user being
"chrooted", as is normally done with ftp users?

You could try mount_null (or mount_nullfs in 5.x), though the man page
gives warnings about bugs.  Or you could simply mount the filespace in a
directory to which "ftpuser" has access.  Or you could create another
user with access to /storage.  Or you could use an FTP server that
supports directory aliases.  I don't know of one that does, but perhaps
some searching would find one.

For your reading pleasure, there's discussion of this for proftpd at

Lots of options.
