our Host application is written in Delphi 10.2+ with roundabout 4-5 Million lines Code each product. Only one product is still written in Delphi 7. Our plugins should be written either in Delphi 10.2+ or in java. We also have a mail client application communicating through a dll to windows mapi system. There came our first 64-Bit issue (not hydra based) that customer use Outlook 64-Bit or Thunderbird 64-Bit. In order to simplify this task i want to release a 64-Bit DLL. But then i need to communicate from Host to Plugin which leads in same issue, 32-Bit Host 64 Bit plugin. The other idea is using java in near future and replace step by step legacy code in delphi. Here we are limited to Java 1.8 32-Bit or OpenJDK 13 (which exist only in 64-Bit). If Hydra could wrap communication between 32 and 64 Bit Host\Plugins it would be a key decision for us using hydra in future official (including more licences since i use a single developer license for my personal experiements). And since its a very basical issue between Bitness-based application also a key feature for other customers.
