I have a PR out for a CLI which interfaces with the network over gRPC [1]. Julian recommended using a package called Avantica which wraps over a standard JDBC+ODBC drivers and takes care the protocol.
The question I have for /dev is if we have a need right now for a standard driver. I could see a use case being that for demoing QS and trying to find users, it would be valuable. Does anyone have comments about how to do interaction with QS? --Marc [1] https://issues.apache.org/jira/browse/QUICKSTEP-87
