Thanks Warren, very good feedback.

To avoid taking up too much of everyone's time at this point, I
think Wladimir's suggestion of placing this in a BIP advisory box for a
while is a good one. We did indicate that this might take a while to
gestate.

It is probably for us to do some further investigations and possibly engage
some input from a few miners.  We don't want to play at being lawyer, but
our review does point towards this being something worth coming back to.

In terms of citation, we did reference a case called *Feist*. We also found
some general database protection details which are relevant to the USA, if
you need any bed time reading:

For now, thanks to everyone for feedback and comments.

Regards,

Ahmed
