of the elements making up the virtual university system, which will be illustrated below. One initial limitation, of a global nature, is the degree of familiarity with the new technologies (computer literacy). By people here we mean both the users of the educational offer and the human resources normally implicated in the process of introduction of the new technologies for the supply of education within an open and flexible higher educational system. There are many initiatives in progress at local, regional, national and international level aimed at overcoming this limitation. Among these, worthy of a special mention on account of its importance and its synergetic approach, is e-Europe 2. Another limitation is the shortage of new professional figures required in the educational centres, and of the various technical figures and those with the necessary organisational skills for the realisation, implementation and management of an educational system based on the new technologies, as well as tutorial figures to provide specific didactic assistance. As will be highlighted below, one effect of the introduction of the new technologies into the educational system is paradoxically the very fact that it will create new and highly important figures of intermediary between the users and the global network system, for which, in the current state of affairs, no appropriately established training courses exist. Another restricting factor is the fact that there is still a very limited awareness of the exceptional economic and social importance of an open and permanent higher education system, characterised by flexibility, ease of access, richness of the educational offer, and permeability between different options. More specifically, we observe how frequently there is an assumed identification of higher education with traditional university courses. The latter, as it is generally currently understood, is instead only a part-albeit still of fundamental importance and with a vast density of potential which is not always fully exploited-of a more articulated and diversified system which goes from the post-scholastic to the post graduate and on into lifelong learning etc. (see Fig. 2). One significant example of the rigidity of the present system is the fact that access to higher education is denied to those who, although of adult age, are without a secondary school diploma, even though their maturity or preparation could be easily ascertained through entrance exams, or through the assessment and valorisation of independently acquired experiences and skills.
