Martin,

I think it would be more accurate to
say that there are at least two different vTPM implementations for Xen
(supporting a diversity of vTPM implementations was one of the design points
from the beginning).

While the vTPM implementation described
in the IBM research report is not available (at least not as open source),
we have discussed releasing in the past. However, we currently have no
plans to do so. We feel that version supported by Intel, based on an existing
open source TPM emulator, should be made adequate for most purposes. If
you feel differently, please let us know.
