In Serbia, for a long time, the only way to use an eID was by having a Windows machine. Over the last year, I slowly implemented an open source module by reading the PKCS#11 standard and sniffing the USB traffic of the official (Windows) module. The result is a shared library that can be used on *nix systems, removing the need for Windows for many citizens of Serbia.
