Desktop on Demand (DOD) is the latest contender to give users a full-fledged remote desktop instead of Web-based applications to help users to stay productive when they are on the move. Similar to Ulteo (which we reviewed not long ago), DOD gives you a full-blown remote Linux-based desktop -- but that's where the similarity ends. Unlike Ulteo, which is based on the VNC protocol and runs entirely in the browser using a Java-based applet, DOD employs the NoMachine NX technology for accessing the remote desktop.
