Quoting Gábor Hojtsy <gabor@hojtsy.hu>:
Anything obvious I am missing or total misdirection I am taking? Better ideas or tips to get this done easier? Does someone see where I'll stop and freeze without a way forward (because certain APIs will not allow me to proceed without major refactoring)? :) If #format a good idea for input format specification on forms, or should I use a better name? (I would not like to get in conflict with #formatter and friends).
Excuse my ignorance in this part of the Drupal code but ... How about adding "${fieldtype}_format" functions to the theme engine that look for hooked "${formname}_${fieldname}_format" and/or "${formname}_{$fieldtype}_format" else apply a default format for that field type?
