Two ideas:
1. (Answer: yes, you can) Have the xf:input reference a separate 
instance than the one you send, use an xf:bind with @calculate, binding 
the one you actually send and calculating with the value from the 
xf:input. The value in the instance should then *always* be the hashed 
password - not just before you submit. I think this is the better solution.
2. Capture the xforms-submit event in your submission and use 
xf:setvalue to set the hashed value. Then, the hash will only be present 
before the submission. You can capture xforms-submit-done and 
xforms-submit-error to clear the hashed copy.
