Could you please define "input" more precisely?

If I understand you correctly you mean the following:

  Current system:

     1. Script drains information from UDD and creates HTML pages
        using some templates

  Your proposal:

     1. Script drains information from UDD and creates some structured
        information in a to be defined format
     2. Another script generates
         a) Current blends pages using the just existing templates
         b) Dynamic pages as they are currently used by NeuroDebian
         c) Some other nifty things

Is this correct?

If I understand correctly than this is quite simple to do.  We just need
to agree about the format and I can easily do the output even in the
current script which enables a quite smooth migration path.  Considering
that I would like to have some "user response system" on the web
sentinel pages which is not possible with the current static pages I
consider to start a GSoC project next year to enhance this anyway which
somehow might be an argument to use a database (with the option to store
this input) as the "to be defined format" mentioned above.

So lets discuss this along these line.  Does this fit your proposal and
what database would you suggest?

Kind regards
