[Dr. Geo] [Bug 1769460] Re: Local area network share

[hilaire]

If it is on a single network this should be doable by using UDP
broadcast announcements. The share server can announce some information
and its IP in a UDP packet being broadcasted. Every client receives that
and then knows the address of the server to connect to

Hope this helps, Norbert

Title:
  Local area network share

Status in Dr. Geo II:
  New

Bug description:
  I am looking for advices on a feature I want to develop for Dr. Geo.

  The need takes place in a LAN, for example in a School computer lab. A
  teacher and students each run their own instance of Dr. Geo. I want
  the teacher to be able to share with her students some sketches. Then
  the students,from their Dr. Geo running instance, can browse and open
  the sketches shared by the teacher.

  The user scenario will be like this:

  - Teacher copies the sketches she wants to share with her students in
  her DrGeo.app/myShare folder. Then she activates the Dr. Geo share
  service (from the setting browser for example).

  - Students start their own instances of Dr. Geo. It automatically
  scans (in the background preferably) the LAN for any available LAN
  shares. When a student goes to File>open she can also browse and open
  the discovered shares.

  - Ideally students could also save their work on the teacher share.

  The constraints:  there is no such things as fixed IP. So the scan is
  over a subnetwork range.

  Any advices, reference reading, traps to avoid?
