==Sugar on a Stick deployability==
The good news is Sugar on a Stick is being successfully used in Schools around the world now! Based on these experiences this is a list of some of the known challenges that people may face piloting Sugar on a Stick right now. September is start of school in the US, so we expect to see an increase in teachers trying Sugar. We want to be ready with suggestions and work arounds as people face these challenges.

It would be great if the teacher could use an inexpensive USB hub to burn more then one stick at a time.

Its working fairly well in the wired network at the GPA lab, but no other use case seem to work reliably.
Its working fairly well in the wired network at the GPA lab, but no other use case seem to work reliably. We need to expand the Poets Guide to [[Collaboration]] to give people hints on how to set up a scenario that will work for them.
===Using a CD helper takes a lot of prep time before and after class===
===Using a CD helper===
Using a CD helper takes a lot of prep time before and after class.
A floppy helper would reduce it. A VM solution might also reduce it. A network boot helper would also reduce it, for PCs that support a network boot.
