There isn't really a targeted platform. There just only happens to be one of me at the moment, and so I've only managed to compile it for a few devices.

As you noted, its not really an IoT databases. It could be used as such, but thats not the reason I built it.

I have also been working on the data transfer problem, because without the ability the share the data it is in fact kind of a useless platform in many applications. I have a job manager being developed that will allow for scheduled or ad-hoc execution of functions. I've also written some small library to encode LittleD results for network transmission. Using some basic networking stack, it would be easy to assemble these pieces into something that could be viewed/controlled from a centralized platform. LittleD could even be modified with relative ease to actually query over other LittleD instances!

EDIT: I would actually like to encourage you to divulge some specific criticism for the IoT application. Are you specifically speaking to your automation system, or to IoT at large? It seems difficult to predict exactly how any one person might apply any given technology.
