Hi Victor

actually there was already some motion regarding this issue. The idea
was to have a common behavior - every time a user would try to close a
project with in-memory layers (i.e. layers with "memory" provider),
QGIS should ask whether those layers should be kept - and store them
in a suitable format on disk (e.g. spatialite) and update the
references within the project. I think it is reasonable to have this
kind of generic behavior directly in QGIS since it is not just a
problem of SEXTANTE.

So we just need someone to sit down and write a patch for that :-)
