We’ve just heard about Serverskine today, an application to track domains. This tool is really handy for web developers, and seems to be essentially a free alternative to Master of My Domain, albeit missing some of the more useful features.
It would be nice to see this become not just free, but open source. It’s a great start, but one could easily add in some of the more useful features from Master of My Domain. In particular, the integration with iCal, so that you know when domain registrations are going to expire. Nevertheless, a great app, and a worthwhile download.
