When I talked to HP's licensing department, there were a $1k licensefee
for anything IEEE1588 related and their message was that even if
the FreeBSD foundation got such a license, the users would still
have to have one as well if they compiled the source code or some
such nonsense.

If this has all been taken care of:  Go for it!
