I'd like to start using Haiku but rely on several applications on GNU/Linux, including one which is closed source. It seems that one way to start using Haiku is as a 'head' OS because I've got GNU/Linux on VirtualBox and already run it headlessly. The question is which technology is most advanced: 1. an X server running on Haiku. 2. an RDP client running on Haiku. 3. QEMU or other running on Haiku. ?
