Ruby on Windows has the win32::ole library that allows Ruby to act as a COM client, similar to VBScript and other scripting languages (Python, Perl, etc. with win32 bindings). However, I am wondering if it is possible to create a COM server with Ruby that can be accessed from other clients. Python makes this possible, even simple, with its win32 package, but I have not been able to find any examples of this with Ruby.
Well, there's always Python, which makes creating COM servers trivially easy. I'm giving up on Ruby for this purpose.
