Use your way, but do it over port 80 or 443. Only the most restrictive firewalls out there would block http or https. https is better if you want to protect your transmissions from prying eyes. I do the same thing in my app. There are actually a dozen or so server commands that the client can issue, for validating the license, checking for updates, checking for messages, etc. The client uses Python's urllib2.urlretrieve() with an https:// url that hits our Apache web server. It then passes control over to our mod_python handler to process and return data. I guess now that you mention it, this is a web service. But I didn't use any special tools or XML or SOAP or anything like that.
