There also doesn't seem to be any support for TPM (Trusted Platform Module). I was wondering if it is due to a general lack of interest and/or personal preference (gcc?) or are there other issues. The reason I'm asking is I'm currently doing a MSc degree in Information Security and was looking into optionally implementing both of the above for FreeBSD as part of my thesis. I would appreciate any input regarding usefulness of such thing. Regards, Igor.
