Depends on what you mean by 'fair'. I think you can now determine CPU
usage in jails, even allocate cores. I think the man pages can tell you
more about that, and the docs on freebsd.org. You can unmask some
devices within the jail and allow only certain jails and users to access
it. And finally I think you can jail a jail now, so that might be
useful- especially in CPU allocation.
Jails will run faster than VBox (or qemu, or VMWare), you're basically
running a specific system which puts it in the same category as Xen
without the Vt stuff so it will run on any hardware you choose. Thats a
very good start anyway.
