This is the same level of security being applied to the CCT's.

Most programs are well known, if a new strong program suddenly appears there
will be questions.

I wouldn't play with a totally rewritten and untested engine either, obviously.

But I would definitely use the one I thought was the strongest, even if I wasn't
100% sure it was the strongest.

Completely untested, yes.
But experimental means you have reason to believe but cannot be sure.

High stakes, what stakes?
The WCCC is for fun like the CCT, nothing is really at stake, nothing perhaps
your honour :)

If the stakes were high, say the winner got $1,000,000 or a match against
Kasparov, you can be sure playing in person wouldn't be enough to prevent people
from cheating.

Where there is a will there is a way, and you haven't thought of all the ways
yet. ;)

Hard, but no where near as hard as programming a world champion program I bet.

Many there are regulars and most newcommers have fairly weak engines.
If we see anything suspect it will be investigated, just as in WCCC.
