I can imagine that when writing a trivial code for performing a trivial
and
well-known function it is quite possible to arrive at a result that is
virtually indistinguishable from the original.

I know that Compaq was forced to do a clean-room re-engineering of PC
BIOS
(two teams - the dirti one with access to real bios athat does
description
and testin and the clean team to write the actual code so that they can
prove they did not "steal" even if the result is byte-by-byte simila)
for
similar reasons

I guess we dont have enough provably clean developers to do it ;)

BTW, teher seems to be some problem with mailing list - I get very few
messages from the list that are not CC:d to me too
