I wrote the original Email because ecasound got stuck even though the
plugins were under /home/sergei/work/ - I think ecasound tries to treat
each file as a DLL and since most of the files are not DLLs, it gets
stuck executing essentially random and illegal code in non-DLL files.

It didn't. I.e. practical recipe with ecasound is to have only .so files
in the plugins directories (I'm talking about Linux here).

I guess 'audacity' performs filtering based on file extension, but it's
just a guess.
