The idea behind the project is not only to collect such information but
rather give users a chance to install it easily as Debian package.

If you would like to improve the description it is the simplest way to
post it here.  BTW, this helps creating a package for Debian because we
could use this in the package description.

Publicly is probably not a good idea because you would undermine a
policy of the portal and encryption is probably not necessary.  But the
problem with registration is the following:  If we publish a Debian
package it is accompanied by the source.  So if there is any strong 
reason for this registration issue and we are just working against this
reason you might run into trouble.

In principle this solution is equivalent to the problem above.  In the
past we had some similar situation with BioImageSuite[2].  The Debian
Med work is done in a team.  My *personal* time is limited and I'm not
really the medical imaging specialist - other pepole in the team have
much better knowledge about imaging.  So enabling these people access to
the sources seems to be necessary to guarantee success of the packaging

Another thing is that there are Debian tools (uscan) which automatically
check for new versions of software.  This will not work if the source
tarball is not publicly available.

That's your choice.  Any publicly available place.

Ahh, thanks.  That's very important.  So if it is simply GPL is there
any reason not to use a repositiry like SourceForge or Savannah also for
the source tarball?

That's really great and you should make sure that you will not irritate
people who helped your project.  So please make sure that they will
agree to the fact that the source will be available without registration
when it will be packaged for Debian.

I think the procedure is like this:

  - verify that there is no problem with publishing the source
  - publish the source in case it will be accepted
  - publish the packaging stuff for the Ubuntu packages (*.dsc, *.diff.gz)
  - please read the Debian New Maintainers Guide[3].  It is perfectly OK
    if you are working on the packaging and one of the Debian Med
    maintainer will sponsor your package - that's in fact that you will
    become a Debian Med team member and an official Debian maintainer
    is checking your work

I hope my hints are sufficient for the moment.

Yes - just do not hesitate to post any suggestion or question here.

Kind regards
