Hi Dima, they already provided me access to several machines, but it is
quite complicated to use. I would like to have an automated infrastructure
that works without me worrying too much but:

- Many machines sit behind firewalls (Sage, for instance). Controlling this
is a mess, specially if you want to push files in and pop them out. Right
now I have a script with 3 levels of indirections to get to some machines.

- Some of those which I use are clusters with frequent outages. Again, the
control software must be capable of recognizing this. Also, using a cluster
typically means delayed collection of data and this is sometimes not too
reliable (the jobs did not run, you do not know why...)

- Some platforms are run in virtualbox images. Starting them up, shutting
them down, controlling that they do not run amok...

- We need to test in windows and this has to be automated. Running the
tests for cygwin or mingw means a lot of time which I cannot spend in front
of the computer. But automating the Windows builds is a nightmare by itself
because of different scripts, lack of an agnostic ssh (*)

So the situation is that I have about 8 different computers + virtual
computers, some of which may be access directly, some not, some are always
on, some not, etc, etc... I am trying to rationalize this once and for all,
but it is hard.


(*) If you use cygwin's ssh, the environment it creates interferes with
that of mingw and msvc, for instance. Cleaning up this mess is complicated.
The only other free ssh which is out there has to be started by hand from a
user account...
