+ * ### Device ###
+ * Device acts a launcher?
+ * 
+ * Acts a logical device.
+ * Though logical devices are not findable by an address as of now.
+ *
+ * Generally a device represents some info about the remote object?
+ * But what exactly? Does it store capabilities?
+ *
+ * In that case I'd prefer it has compile time information about
+ * those.
+ * 
+ * ### RpcServer ###
+ * Should always be created on the side which it is run on.
+ * For SYCL it's kernel launches, so it's created on the local
+ * thread.
+ * For Threads it's supposed to be created on the remote thread.
+ * How do I solve this cleanly?
+ * Technically the server shouldn't know about the device.
+ * It should register with an authority, so it gets requests
+ * though.
