[Libreplanet-dev] license issues

[Peter]

While researching for the website proposal I came across the postgresql's 
position on their license, which is BSD. One discussion 
http://archives.postgresql.org//pgsql-general/2000-07/msg00210.php clearly 
shows they would not consider any other license. Today they're still BSD, but 
I don't know whether their attitude has changed.

I am beginning to suspect key software is not free, despite the 'vast number 
of programs' under GPL. My issue isn't with the license itself, but whether 
the developers are pro Free Software.

I had a look at savanah, savane, gna!, and quagga, but they don't seem to be 
well maintained.

So, to what extent do we limit ourselves to pro developers in building Libre 
Planet with free software (as opposed to open source)?
