Besides questioning the rationale of the whole approach still, I'd anyway not 
be too optimistic wrt calypso, if we keep in mind #1024 e.g.

One word for clarity: GERBER is *useless* as you can't reasonably edit them. 
It's all about project files. How would you implement any change in schem to 
gerber? Edit the traces', vias', component placements' description by hand to 
represent the changed schematics?
If you were to edit a large document, you wouldn't start the job by looking to 
the postscript-file ready for transfer to printer. Same with gerber, it's 
just pcb-"printer's" postscript.
