Hi Power;
I have developed Appeon based applications for various Canadian Government departments and private industry. Please feel free to drop me an email and I can give you more details. I have also built an application framework for developing Web & Mobile applications for Appeon as well. This framework is in use by many organizations world wide and known as the STD "Integrated" framework (STD Foundation Classes | SourceForge.net).
FYI: I will be speaking about the framework and many of my Appeon appreciations at the Charlotte PB Conference in May, 2015. NCPBUG | North Carolina PowerBuilder User Group
