At the moment I see no possibility to avoid TLS - so either engine or
plugin. In fact, in case of Java (and I think in .NET too) it is not
that hard to use TLS in plugin... as to the Delphi support - things
might be trickier there.

So, from Java POV I'm ok with current API, but I see no solution for
Delphi without TLS.
