While this seems attractive at first sight, we cannot produce a game with no add-ons without excluding a section of the playing community. There is a minimum set of mods that's needed to bring CivIII 1.29 and PtW to the same level playing field.
However, the staff hopes to continue to develop new ways to surprise you, so I suggest you continue to watch this space.
If bandwidth is the problem I think I've suggested to you before that there are other ways to solve that problem. For example you may be able to persuade someone local to you with broadband to burn the mods to a CD and snail mail it to you.
