Just to let everyone reading this thread know, I just took a picture using Python, using the Miso Library linked off the wiki page mentioned in the first post.
From the posts here, it didn't seem that people were aware of this module.
Here is their test_camera.py sample code (in the Miso src download).
def write_file(fname, fdata):
fp = open(fname, "w")
data = miso.take_photo()
print "got %d bytes of data" % len(data)
