PLPN stands for Program for Local Presentations using the Network system. The team from Thailand designed a system which helps several people share their own presentations to only one presentation server, without the hassle of exchanging the files.
This system is very useful in:
- professional environments, where several team leaders present their achievements
- schools, where several students present their project work to their peers.
More useful features include:
- Multi-OS support (Windows and Linux for now), which is a common occurence in most groups.
- Adjustable resolution, with most screen formats already supported.
- A nice and pretty download page on the server, which is optional (and requires an Apache HTTP server).
We were surprised to find out (in the end) that the presentation was delivered using PLPN. The team had 3 laptops: the server, and 2 clients: one with Windows and one with Linux.
Suggestions for further development:
- Try not to send the whole screen to the server, but only the differences between the current and the previous screen.
- Try compressing data over the network. Maybe you will notice improvement.
- Create a user for the moderator (choose a computer, end a session etc)
- Show the connected computers on the server as separate windows
- Autodedect the connection speed and adjust bandwith usage.
