Replying to a message of Richard Vonzel to All:

 RV> I need a key for fastecho. Someone must have one for sale.

Tobias Burkhardt owns the software.  He has a company Software Technik Burkhardt.
He lives in Germany and AFAIK he's still around.  Try Google.

Used to cost about US$30.  I used an international money order (from a bank, USPS
international money orders aren't accepted in Germany) but he may still accept credit
cards.
