Yes. While one can prevent re-adding of rows if table has a primary key is
of type identity and this is used to compute the hash, I do not see can one
can have proof of unauthorized deletion of rows.

BTW, I've tried (unsuccessfully) to make something like tamper-proof tables
(records, as I see now) using computed columns here:
http://pastie.org/3051925

Some of the behavior/errors do not look exactly OK to me, but since I have
no use for it right now, I'm not that concerned.

On the other hand, tamper-proof tables/records may be a nice feature to
have and if H2 Roadmap is not big enough...
