Yep, because I added some code recently so that would
"just work". Doing attach DATA+"foo" won't, since attach
isn't smart enough to evaluate it's arguments.

If you attached e.g., a big table of numbers foo.dat, and
in your python code wanted to do
open('foo.dat').read()
it would fail, since the open command is not run in the
DATA directory. Instead do
open(DATA + '/foo.dat').read()

True.

True.

3. There is also a way to edit a file under Windows and have
it automatically get uploaded via scp into the virtual machine
whenever it is saved. I think http://winscp.net nicely supports
this.
4. Using VMware workstation's "shared folders" feature, which
makes it so sage under vmware can read/write the files
that you have under windows, then use a standard windows
editor on those windows files.
If you can set it up, I think 4 is the best.
