A number of people took the time to email me their thoughts regarding my rant regarding source code for QuantDeveloper. Anton from SmartQuant responded, but unsurprisingly, I havn't heard anything from QuantHouse.
It seems that QuantHouse has purchased various rights and such to QuantDeveloper, and have renamed it to suit their suite. SmartQuant has also retained certain rights and such to QuantDeveloper, and have maintained the name. SmartQuant has indicated they are continuing development of QuantDeveloper and has hinted that some quite advanced features are in the pipeline. He also confirmed that, for existing developers who have subscribed to source code, source code is available for new releases.
