Her var hvad jeg sendte. Det sidste punkt fandt SourceForge en bedre
løsning på (publicering i avis).

Jeg vil tro, at dette faktisk er en ide, man ville kunne patentere - altså
at man en gang i fremtiden kan bevise, at et givent dokument (filen med
MD5-summe) eksisterede på et givent tidpunkt i fortiden uden nødvendigvis
at have offentliggjort dokumentet i fortiden.

Men at Hartmut er kommet frem til en lignende ide inden for et par måneder
uafhængigt af mig beviser netop at det ville være urimeligt at give mig
patent på ideen.

Subject: Software patent database on Sourceforge?

Hi SourceForge.

In
http://www.salon.com/tech/feature/2001/03/21/open_source_patents/index.html
is says:

"For a fee of $20 per document (a significant discount over IP.com's usual
$100 fee), software inventors will be able to place their innovations in a
searchable software database."

What we need in the free software society is not really a searchable
software patent database, but a database with date stamped source code
that can hold up in court.

I am thinking something like:

* Make an MD5-sum of every changed project daily (If unchanged: use the
  MD5 of yesterday)
* Burn all the MD5's on a CD-ROM.
* Compute the MD5-sum of the whole CD-ROM
  The CD-ROM goes to an official institution that can testify to have
  received the CD-ROM at a certain date and that will be willing to
  testify so in court. They should also sign an agreement that the MD5 of
  the CD-ROM is what the MD5-sum happens to be.
