When doing urlopen, you will want to use timeoutsocket.py (included in
newer versions of python (or zope), found as a simple file on the web in
the ol' times of zope 2.5.1. Without this your connectiion will just
hang at the urlopen command, *as there is no timeout*.

Also look out for what others have aid in respect to https, no
expirience with that myself. 

There are some applications for Plone to use PayPal (PloneMall /
PlonePayPal), you might want to look at these for sample code too.
