Thanks Simon for your contribution,
we all have our favourite tools and like exploring new alternatives. The top 3 you have listed are my favorites too and we already use them at my institution.
It will be good to keep the discussion about tools and technology contained here - in this forum as the main focus of this seminar is on designing and developing the AVI framework - wich is more concerned with process and people than tools at this stage.
The time exploring tools will come and all the information and input gathered in this forum will be quite useful then but is premature at this time.
