+ * 2. Starts listening on all of the transports and returns a URL (maybe a promise too? Not sure whether it should be a promise or event emitter. Maybe both?)
+ * 3. Once it recieves a message, decrypt it and resolve the promise with the message.

+ * 2. Encrypt the message
+ * 3. Send the encrypted message to all of the transports that are in both the requestURL and the list of transports.
+ * 
+ * Possibilities:
+ * - Non-ephemeral. Keep listeners alive to allow for multiple requests
