Thanks for the GNUe reference, I wasn't aware of that project. It
occurred to me that they might have addressed the re-denomination
problem already, so I subscribed to their list and asked.
It turns out that the section you quote is just a proposal to start
discussion -- they have not decided on a specific solution yet. They
also had not considered currency redomination. At any rate, the first
response I received basically summarized our main proposals :)
The poster (Reinhard Mueller, one of their main people, I think)
leaned toward creating new currencies as redominations occur, but
there will probably be more responses.
Given the commonalities between our two projects, I'm hoping we
will be able to share our work in the future.
thanks,
dave
