[slicer-users] Windows Server 2008 vs XP,Vista for Slicer

FWIW, XP and Vista both have the capability to support concurrent
sessions, but it is blocked by default in most/all licenses (ultimate
might allow). There are various discussions and "solutions" of this
available online, though Server 2008 would presumably be better for
production purposes. 

You might want to first try Slicer out remotely from XP/Vista to see if
it will suit your needs (doing so will lock out the local user
temporarily). The underlying RD protocol is the same as used for 2008
server. There might be better performance with better
hardware/network/settings, but when I have run Slicer over RDP it is
essentially unusable for any kind of 3D viewing work (ditto VNC).

It works and allows multiple users to login and use the system through Windows Terminal Services and the Remote Desktop capability.  It works well with the exception of no accelerated graphics.  I am sure this will improve in the future, but to my knowledge, the remote desktops utilize software framebuffers, so that remote users will not be able to do accelerated volume rendering.    The interface feels a little slow when interacting with the 3D windows and quite slow volume rendering, but otherwise OK.   The slow interaction will be the case with most any remote technology.   Hardware solutions (e.g. amulethotkey.com) are required to get around the speed limitation.
