one of the interesting new feature of Oracle Solaris 11 Express is the Network V12n
this is based on the crossbow project, as the design and arch docs there are many presentation, blogs and workshop that were based on OpenSolaris
Some cmd dladm options has change and OS11x support ipkg and solaris10 full root zone
The Network v12n doc is here, keep in mind the VM is for x86 and Network V12N apply to both x86 and SPARC.
Solaris zone work with Network V12N, but I did not see any talk net and VCC and Vdisk
