I think that was for my benefit. I still like port-number better than
number. It doesn't get much more vague than "number". Maybe "port-id"?
Or just "id"? Is it important? Are you worried about saving space?

I don't think that is possible with the current LADSPA standard.

That is legal in XML. The library I use (libxml++) output the more
verbose <port></port>. I think the library could read the shortened
format. I didn't worry about it.
But basically you like? I think the main question is where to put the
presets. "/usr/local/lib/ladspa/preset/ladspa_plugin_id/"? That works
for me as a fine default. But should user created plugins be put there?
I'm leaning towards having two directories. One for presets distributed
with the plugin put in /usr/local/ and one for presets created by the user
saved in a local directory. Maybe ".ladspa"? A little more work for us
implementors, but I think it would be cleaner.
