Try ClientForm (http://wwwsearch.sf.net/ClientForm).  Untested:

import urllib2, StringIO
import ClientForm

url = 'http://blah.com/wherever/your/form/page/lives.html'
r = urllib2.urlopen('http://blah.com/wherever/your/form/page/lives.html')
forms = ClientForm.ParseResponse(r)
r.close()
form = forms[0]

filename = 'c:\temp\file.cif'
f = open(filename)
form.add_file(f, 'application/octet-stream', filename)
r2 = urllib2.urlopen(form.click())

print r2.info()
print "********************************"
print r2.read()
r.close()
