1) what are the "ultimate" systematic uncertainties which can be achieved at the B factories? What are the limiting factors in the evaluation of systematics due to the detector, the analysis method (e.g. mES fits), signal knowledge, background knowledge? Are there any uncertainties which have been overlooked in the past (e.g. D** composition and form factors)? Are there any improvements foreseen from current and future experiments? 2) It is now possible to perform measurements on vast regions of the phase space. What is the subsequent impact on Vub uncertainties? a) Do we really need to worry about Weak annihilation? Is it really such a big error? b) Why including more phase space does not change the error on BLNP? c) Almost all methods proposed to extract Vub, seem to agree when the measured phase space is increased, except one; is this telling us something about the validity of this method? d) Can we use the analysis with more phase space (~90%) to at least reduce the numbers of Vub extractions we use? 3) It is in principle possible to determine experimentally separate branching fractions for charged and neutral B decays, although with sizeable (~x2 wrt current breco analyses) uncertainties. Are such measurements and uncertainties useful to study weak annihilation and other effects? 4) Which HQ parameters should we use? How should we determine them? Global fit with or without b->sgamma moments, b quark mass determination from PDG, etc.? 5) What is the theoretical uncertainty on ratios of decay widths for different cuts in the phase space? Can we check the theoretical calculations by measuring these ratios experimentally? 6) Would it be possible to converge on a single Vub determination by using a theory calculation and cross-check the result / assign an additional uncertainty by using the other three? Would the outcome of 2) and 5) be useful for this purpose? Are there any other independent checks possible? 7) What is the optimal way to combine data from different kinematic regions (shape function, OPE region) to determine Vub? 8) What are the irreducible theoretical uncertainties for the different methods of extracting Vub? 9) What is the optimal way to determine the shape function with reliable uncertainties? a) How big are subleading shape function effects? b) What are the uncertainties from nonlocal (at the b scale) physics? 10) Are there any more useful perturbative calculations required to reduce uncertainties in Vub?
