What about VNC+?
Sorry to add yet a third option, but I'm looking for remote software as well. Just from reading, it looks like VNC+ can be used with Linux clients, while RDM+ is limited to Windows. I need to access both clients, and it looks like I will be giving VNC+ a try in the next few days. My main consern is that I've experienced speed issues with VNC in the past.
Does anyone use RDM+ to access a windows workstation, and then remote into a linux client from the workstation?
