We've been talking about a new dm ioctl for passing arbitrary commands 
to a target, which I think would cover this.  

[Pass in device name/uuid plus offset within device and arbitrary ascii
command, and then the ascii command gets passed to the target at that 
device offset.  It would be up to each target to define its own 
commands.]
