Hello,
And thanks for your kind words.
Yes, pretty much. If your coin is a clone of Bitcoin that retains most of its JSON-RPC API intact, then it should be just a matter of replacing strings. You can start from the litecoin adapter which I consider the reference implementation.
From time to time I update the litecoin and other adapters. Simply remove the ds-update.php file before redistributing your plugin extension.
