+ adds the run in sandbox extension to nautilus
+ copy to .nautilus/python-extensions

+
+sandbox:
+ adds support for file checking, This was working I don't know why it didn't at that presentation
+ adds support for file relabeling, This is/was also working.

+ This is pretty much the most basic condor wrapper you can create, it requires the -f option in sandbox. Also I can't make this work, maybe the grid team will have more luck.

+Run the

The seunshare command unshares from the default namespace, then mounts the specified homedir and tmpdir over the default homedir and /tmp.

+Use alternate tempory directory to mount on /tmp. tmpdir must be owned by the user.
+.TP
+\fB\-c cgroups\fR
+Use cgroups to control this copy of seunshare. Specify parameters in /etc/sysconfig/sandbox. Max memory usage and cpu usage are to be specified in percent. You can specify which CPUs to use by numbering them 0,1,2... etc.

+Multiple machines that need the same customizations.
+Extract customizations off first machine, copy them
+to second and import them.
+
+# semanage -o /tmp/local.selinux
+# scp /tmp/local.selinux secondmachine:/tmp
+# ssh secondmachine
+# semanage -i /tmp/local.selinux
+
+If these customizations include file context, you need to apply the
