Well there are many factors here. First of all patents only cover select
areas of the world. Secondly they might formally have been made
available under terms that makes them usefull for people in certain
circumstances. Thirdly they might not be enforced, which might sound
like a cop out, but I think if all software patens where upheld the only
software developer in the US would be IBM.

The LGPL allows linking to non-free stuff

Well the logic here is that an application is only covered by the license
of plugins they use, so if the beep is an unencumbered wav then you are
fine. If the beep is a mp3 however then I would say yes.

We think they often can be legitimately used, but not by GPL apps.

Think I covered this earlier.

We are trying to be consistent. We started by adding a license field to
the plugin factory information to help developers see what kind of
license a plugin is covered by. Secondly we have now started this drive
to relicense applications to the LGPL, starting with gst-player that we
have relicened and which next release will be LGPL
THe basic issue is that we want GStreamer and GStreamer applications to
be as legally unencumbered as possible and shipable by as many companies
and organisations as possible. To do this we are trying hard to
accomodate the wishes of Red Hat, Sun, GNU, international law and so on.
Personally I think it is a quagmire we probably never get completely out
of, but it is still important to try IMHO
