[Spice-devel] multiple users and xspice

[Rob Verduijn]

Hello again,

I managed to get the spice-html5 working ;-)

Sadly the changes and scripting to create what I want is a bit of a
challenge for me, but the real downer is that it would be a custom
implementation.
Maintainability will be a challenge for everybody who gets to manage the
system after me.

Thanx for your help.
Rob
