The goal of the system architecture is to provide an infrastructure for VRET related projects so that we
- provide the therapist with basic feedback like video, sound, heart rate
- provide programmers with a common approach and tools to handle remote therapy
- enable re-use of commonly required components
- easy switching between various therapies
The figure below shows the first proposal we arrived at after meeting with Willem-Paul, Niels, Christian, and Daniel.

Network Mechanism
To handle communication between the patient monitoring system and the patient computers, we currently use plain sockets. While fast and simple, this requires all firewalls on the route between server and client to be open. Usually these ports will not be open except inside a single domain. Opening them will require negotiations with the network security staff and seems better avoided if possible.
I discussed this issue with Ruud, Tim Verwaart, and a number of people in the computer graphics group. Our safest bet seems to be using the HTTP ports instead of just arbitrary sockets.
One possibility is xml-rpc. A number of people in the graphics group working often with this do recommend xml-rpc.
