[Ardour-Dev] Export to "Master" track

Just to make sure before I start on this. No one sees any immediate
issues with the following:
Complete export logic. Single click. Button = "Print session"
1: Disable transport
2: Freewheel and export the Master track to disk,
3: Import the resulting wavefile as a region into "Master" Track
4: Create the peakfile and display the waveform in the "Master" Track
While playing logic.
1: The Master bus outputs -> Master Track inputs.
2: Master Track = Tape mode
3: Record while playing.
1: Select an area of the "master" track
2: Click "Print session" button
3: Export selected area to disk in tape mode therefore overwriting the
previous data for the selected area.
4: Re Import and display waveform
1: Preference = "Enable Master Track"
2: Master Track is bound to the Master Bus so that they both move around
- Can anyone put a guesstimate on how long this would take to code? I'm
guessing about 2 weeks (80 hours) of programming for someone who knows
the code and maybe two months of twiddling for someone who doesn't?
