True. What I really ment with my challenge, was to show that there
are ways to circumvent the Bound even without introducing unknown
physics. One of the most obvious would be to let the energy increase
in a region without limit, that would enable an infinite amount of
information (this may happen during the Big Crunch).

Perhaps. But it has been rather quiet on the string front, I think
the theory got stuck in mathematics and didn't get to the physical
side. Still, some results are fascinating.

Yes, this is the most important problem to be solved. Personally I
am more interested in non-manifold possibilities; who said spacetime
is continuous?

Exactly. There might be "information horizons" in physics, levels of
structure that information cannot flow well through (such as the
quantum level; the strings may have their own working information
systems, but cannot interact in any useful way with the emergent
structures on a larger level, which cannot influence the strings
since they are epiphenomena).
