Completed on Jan 9: The current zip packaging system uses a non-open-source component (TZipForge), so it undermines the OS nature of IMT. It's possible that the DelphiZip component (Lesser GNU) could be used instead. I've already downloaded and installed it; I need to make an attempt to mirror the good functionality already achieved using TZipForge with the DelphiZip component, and if it looks feasible, replace the former with the latter in IMT.
