I am here from Virtua Drug Ltd (or our new name Domain Science).
The thing is that we don't support .in backorders on AutoBackorder at all at the moment. First, because it seems a registrar cannot be involved in dropcatching and we have our own registrar. We would have no problem providing backorder services for registration fee but it is not clear that it is allowed or not.
And there is another rule, a registrant can only have 2 .in domains (we have to contact the CEO of the registry for approval for each registrant if they have more, which we are not willing to do). So it is basically impossiple to provide dropcatching service without breaking these rules. I know there are many registrars out there who are doing it, we don't.
As for DesktopCatcher, I don't know what are your privacy concerns but we don't monitor the activity of our users at all, not even for collecting statistics or anything. We don't know what our users do. One secret about the licensing fee: we don't disable keys even if your subscription has expired. It is just no business to provide full support forever for a one time fee, that's all. So you can use DesktopCatcher and than cancel your subscription after a month, it will work. With Dynadot API or OnlineNIC or RRPProxy, you might catch some .in domains there.
We don't update the software too often and there is a serious reason behind: not the software but the APIs catch the domain. It makes no difference if we recolor the software each month, the strength of the APIs will decide if you can catch a domain with the software or not.
