I don't get it, there are tons of unanswerable questions ( well, besides "I don't know" answer..)

You can even scan through SoPW and you'll find lots of questions without answers

Things like - how to pack Gtk-based perl script with PAR ( doesn't work, nobody works on it, there are few known bugs left to be fixed )

or maybe how to connect to TLS-enabled ftp servers with perl ( you've got to roll your own client (or get one from me;), or use c/c++ library like ftplibpp )

or how to expose your SOAP-based service to C#/Delphi/ other static langs ( requires lot's of knowledge of WSDL and manual tweaking and writing your own WSDL description )
