Thank you, Martin, to give me some hope ! "" Alternatively, run one or more copies of Windows in virtual machines on a *nix system and access them remotely via VNC or ssh with X.11 forwarding. "" - What are those virtual machines used to run copies of Windows? Something similar to Wine ? Specific SW packages simulating PC HW ? - copies of Windows : as standard Home XP for instance ? - could this *nix system be the host of my website ? - my Joomla-based website offers "wrapping" of an iFrame to another application : could this application be the one running on the copie of Windows ? thus forming a bridge for selected users to access this Windows application ? Is all that too much speculative ?
