There's been a bit of a misinterpretation here. Loading your game into RAM is legal. Violating the EULA is illegal. The EULA for World of Warcraft says that you may not copy the game into RAM (run it) while glider is running. So, if you run Warcraft first, then Glider, it's perfectly legal.
However, glider must invoke Warcraft, so it knows which data is stored in which memory locations. So glider needs to re-code to attach to a running WoW, instead of doing the executing itself.
It should be noted that we have no idea if Sun doesn't already have an appropriate license from Novell (if they even need one at all). But, if not, we may see some messy business between Sun and Novell, and correspondingly OpenSolaris and Linux."At one time, Sun was an SCO supporter. [...] Sun's Jonathan Schwartz — then Sun VP of software and today Sun's president and CEO — said in 2003 that Sun had bought "rights equivalent to ownership" to Unix.
SCO agreed. In 2005, SCO CEO Darl McBride said that SCO had no problem with Sun open-sourcing Unix code in what would become OpenSolaris. "We have seen what Sun plans to do with OpenSolaris and we have no problem with it," McBride said. "What they're doing protects our Unix intellectual property rights."
Sun now has a little problem, which might become a giant one: SCO never had any Unix IP to sell. Therefore, it seems likely that Solaris and OpenSolaris contains Novell's Unix IP.
