Sounds good. I was giving the gstreamer plugin preset stuff just as a
source of inspiration. Also because there is some beef in tehre how to
handle system wide and user local presets, updates of any and so on.
As Paul said for ladspa there is no library and thus we shoudl agree and
simple conventions, the exact format does not really matter as ladspa is
so simple that there are no hierarchies etc.. An ini file would be
totally fine. what about:

[ladspa preset]
version=1.0
plugin=<plugin-name>

[<preset-name1>]
<key1>=<value1>
<key2>=<value2>

[<preset-name2>]
...


If we are happy that its not allowed to name a preset "ladspa preset"
(would conflic with the header) this would already work I'd say. This
way we would not even have extra files for each preset. On the other
hand I am fine with having one file per preset too.

[ladspa preset]
version=1.0
plugin=<plugin-name>
preset=<preset-name>

[parameters]
<key1>=<value1>
<key2>=<value2>
