I don't know what you mean by "debug isntance":  is that from within the
process started by 'zopectl debug'?  from a script run via 'zopectl run'?

Use 'isinstance HTTPServer'.

Yes.  There will be one instance per '<http-server>' directive in your
zope.conf file.

Rather than guess, I would make the "callback URL" an explicit
configuration item.  You could set an environment variable with the
information you need, or add a custom stanza to zope.conf, e.g.::

    <product-config your_product_name>
       callback_url http://zope.example.com:1234/path/to/callback_method

You would then use this value via

See the bottom of $ZOPE_HOME/skel/etc/zope.conf.in for more information.
