While I was searching around again I came across this information about a commercial boiler.
I have been thinking about this too: you could gently simmer the wort for the first 3/4 of the boil time and then give it a good boost for the last 1/4 of the boil. Especially if you could heat only one side or the center of the wort to maintain a good circulation. The latter is needed for the hot break.
The 1st stage will give you the majority of the SMM -> DMS conversion and the later stage will boil it off while using less propane than you would have when maintaining a vigerous boil all the time. it would also lead to less color increase during the boil due to the reduced thermal loading.
I have not tried this, but am intrigued by it since it also means that it would be less likely to boil over in the beginning. And I could even leave the boil pot partially covered for the first stage, saving even more propane.
Just food for thought.
