We are now installing INGRES version 6.2 (including INGRES Net on SUN 
(4/490 servers and SPARC SS1 diskless work stations) and have some questions 
concerning the best way to organize the use of INGRES for a large number 
of students.

1. Registration and deregistration of students as users of INGRES/Net.
   INGRES should be available for each of the students (about 200 students)
   from each work stations (about 30). As we have understood it, a
   student must register as a user of a dbms on a certain server each time 
   when he starts using a new work station. Since most of the students are
   casual users of INGRES we would like to avoid the registration on the 
   net. Is there any clever way to achieve this? Note that each user is 
   supposed to use his own private database. 
2. When using INGRES Net a number of processes are presupposed both on the
   clients and the server (e.g. iigcc and iigcn). How often does any of 
   these processes "die" ?
3. Which are your experience of the load on the server/network when for 
   example 15 - 20 students are developing applications by means Application 
   By Form, etc. simultaneously. 
4. Have you any experience of Windows 4GL in an XWindows environment?
