Conclusions

• develop IT staff capability
• sustain and institutionalize the networking
  effort
• support the development of network applications
  and services
• develop policies and guidelines for the
  management and use of network resources

The real challenge and more difficult task lies
ahead, that of creating content and activity over
this evolving network.
