What's the most efficient/fastest way to securely get data in/out of a jBase system?

The last time I had to do this, we wrote a CGI interface and accessed the system via HTTPS. This time, we have no need for the full CGI environment, we just need to parse some JSON data, and return a JSON response. 

Similarly, MVIS is overkill. Is there a "jClient", like there is with qm?

We could just listen to a port, but the inbound connections will be coming from multiple clients, so we really don't want to run multiple transactions through the same process. We like the statelessness of separate connections. 

Since jBase apps compile to OS executables, the current thought is to establish an ssh connection, with keys, run the appropriate routine, return the JSON and then exit. 

We're wondering if there's something simpler.
