Wahou! I did not plan to start such a debate...

The problem is not how hard or easy it is, the problem is how time consuming it is.

I am pretty sur that I will manage to make it work. But when? I allready lose three hours Friday and two hour on saturday... That's definitly too much. Because I am not an engeneer in computing, I am a researcher. To make my research, I have to be expert in longitudinal data, in clustering, in anorexia, I have to speak english, I have to know R, and C, and package managing, and LaTeX, and gimp, and... and... and... There is so many things to know... I can not be expert in all.

So I do not have time to (and I do not want to) explore all the ssh subtulties... Worse, I have a project, I manage to find some people that want to work on the projet (but that also have a lot of other staff to do), I do not want them to give up because it will take to much time for them to make ssh run.

Generalier, I think that anything should be done to make tools easy to use for non-expert, because more and more R user are occasional user. They are not experts, they don't want to become expert. They are just feed up to pay a lot of money for SPSS or Stata... But I guess this is another debate.
