I don't know of an "easy" way to edit it, but you could look for the corners
of the east and west coastlines and slice out big sections of coastline
detail. A graphical editor would be handy (or a translation into a format
which has a graphical editor), but it might not be as bad as you think.

The Java virtual machine may well be using 300 MB (it's a pig) but the
Osmosis app itself is probably using less than 100 MB, I'd guess.
