Adobe non free code in type 1 fonts

The problem

Font hinting uses some proprietary code from adobe. The non free code is described here:

Lintian help see report here

Install the t1utils package and run the following command on the pfb file:

t1disasm file.pfb

Check if you see the non free code.

Rewriting is difficult:

the adobe code is part of the language
some printers search and replace the adobe code by their own routine. Rewritting this code could crash your printer.
the adobe code is buggy (leaks memory) and postscript interpreters patch it at run time. Modifying it could change the postscript interpreter behavior.

Adobe seems willing to relicense see mail here.
