Pluses:
- Loads of documentation
- Lots of assistance across the spectrum of users; educational users and as well as products specialist.
Its an out of the box implementation. All you need is some HDD space to house your filesystems (we used LVMs) that will be built.
(I think you understand why LVMs are important in areas where there is unexpected-uncontrolled growth for user needs.)
With your current expertise that I've witness from your netbook understanding, this is a no-brainer for you. I expect that more of your time will be in initial reading, than actual download, setup and use. Its a guided approach. LTSP PCs on the LAN are dumb. There are an average of about 50+ simultaneous users in a defined user base of 200+ people on a 4GB RAM dual-Xeon server and its is not close to max, currently. Edubuntu comes with a full complement of Office/Classroom tools for students and faculty. Expansions are planned this summer.
Hope this helps.
We are trying to determine if we can securely allow off-site, over the LAN access directly from the internet. Right now, we are using a Microsoft Terminal server as a helper to get internet user connections to the Edubuntu ID.
Hope this helps.
P.S. You are absolutely right about Puppy not be an attractive platform for something like this.
