Yeah i know about KParts, however KParts is more limited and the tech is only about KParts whereas COM is used for a lot of things, including even stuff unrelated to the GUI (e.g. Active Scripting). In addition COM defines a binary interface for accessing objects that can be supported by any programming language that can support structs and pointers whereas KParts is only for C++.
