hi,
the system that we are using for canada, works great.
and it will work great in an emergency for fast mapping an area.
the constant variable is in the grid system, an extention of the nts
system with quad-tree tiling.
all .osm data is split into managable squares, small enough for 1
person to handle at a time.
the googledocs chart showing this data is updated in real time and
also has an instant chat feature.
irc chat, while working also is helpful, for instant feedback.
the chart system can handle multiple datasets.
it would also require a little 'give' from osmland to permit the
uploading of a tile grid, since degree lines are not possable in josm
to view, and listing the area grid system works.
i have never done archeology, but the way to view a archoligical dig
site is the same. each square in the grid is numbered.
..... thankfully, computerteddy already has the planet #s for 1x1 degrees.
my 2 cents.
im on the #osm-ca sometimes if anyone needs moreinfo
