I would say it's currently usable for one-shot stuff, but probably not 
reliably useable for automated things without some kind of 
administrative oversight.  In theory, it wouldn't be hard to write a 
script to automate fixing this particular issue when send encounters it, 
but that has it's own issues (you have to either toggle the snapshot 
writable temporarily, or modify the source and re-snapshot).
