Hdb seems like one of those interesting components that could be quite useful. Apparently it's a history database that runs on all robots so a probe can store and retrieve recent information.
Unfortunately that's the full extent of my knowledge on the probe and it's largely undocumented. Anyone ever use the resource or know any more about it? I'm inclined to use SQLite or something rather than start down the path of using some black magic undocumented resource not knowing what I'm going to find. But if it's cool, maybe I'll use it? It might even be cool for IPC in a process pool or something reporting on dispatched transaction results?
