Just a thought: You'll have your own processing routine to go along with your 
new record type anyway. Therefore, you can have your processing routine be smart 
enough to only actually talk to the hardware when the "ready to go" field has 
been filled in. Any other processing would just update the necessary fields in 
the record.
