This does indeed allow the client's screensaver to lock the SunRay session, but
unfortunately key sequences like <ALT><TAB> won't get passed to the ThinLinc
session any more but are interpreted by the client's window manager instead. I
realize this is the documented behavior, but it makes the workaround a
not-so-ideal solution for us...

We're currently using XFCE for the ThinLinc session and a quite old KDE 3.5.10
installation as the SunRays desktop. From what I've been able to find out so
far, its kwin window manager should be complient to EWMH DRAFT 1.2, at least
that document is bundled with the KDE source code.
