To save you the two-link chase to get at the meat of the announcement, here's a direct link to the paper: http://info.iet.unipi.it/~luigi/papers/20160205-tlem.pdf

It explains in a lot more detail than the mailing list post what TLEM is about and how works.

Choice quote from the abstract: "Our emulator can handle bidi- rectional traffic at speeds of over 18 Mpps (64 byte pack- ets) and 30 Gbit/s (1500 byte packets) per direction even with large emulation delays."
