"Retour" de http://bellard.org/. Il avait émulé un PC sous DOS en Javascript. Là c'est donc le PC sous Windows XP en Java !
Avec quelques restrictions, genre le disque est émulé et accédé à distance ... mais chapeau bas ! Très très très bas !
Attention, c'est assez lent quand même sur une petite config.
Par là donc:
avec XP ou Ubuntu "émulables"

What is JPC 2
JPC2 creates a virtual computer on which you can install your favorite operating system. JPC2 is a pure java software emulation of a standard PC's hardware, and all code stays locked inside the Java Applet Sandbox.
Without any native software and/or reliance on hardware supported virtualisation/paravirtualisation, JPC is the safest way to run untrusted, unreliable or just old unsupported software. With Windows XP no longer in mainstream support (all support ending in 2014), Intenet Explorer 6 already unsupported, many businesses are either left running essential software on unsupported operating systems or swallowing hard and upgrading IT infrastructure (with all the costs and risks that involves).
JPC2 is the latest version of JPC project which has been substantially updated to be able to run Windows XP and Ubuntu Linux, both in original unmodified from.
