Several TNC implementation were presente @ InterOp (Las Vegas). The TNC is a multilayered standard which can be implemented on top of other technologies, including IEEE 802.1x and SSL, but currently only bindings exits for tunneled EAP methods. TNC provides interfaces for integrity data collection, verification, transportation and policy enforcement.

Press coverage of the event can be found here and here.

A TPM compliance study at the HGI institute for IT-security (Ruhr-University Bochum) show that some of the studied TPMs are not fully compliant with the TCG standard, due to some bugs.
The study is interesting, but somewhat misleading in certain aspects. As an example, AES, DES and 3-DES are not required to be supported by the standard, so I am unsure why they appear in the table. The TCG compliance tests are only checjing the existance of seven known TPM bugs as far as I understand from the report.
