Hey @Greg_Schleusner!
Let me start by welcoming to our community! Feel free to Introduce yourself 🙆 if you feel like it 
As for the Receiving end of things… as Dimitrie said, there’s some work pending on our side to allow the Receiver node in grasshopper to understand what a transport is and how to deal with it.
This is part of a pending architecture change in how transports work throughout Speckle, so we’d be happy to hear any insight or use case you may have in mind.
The local send/receive nodes work exclusively with the local SQLite DB inside your Speckle folder in %appdata%, but nothing else.
If you’re keen on the technical details, you can find a longer explanation here
