In the same boat with regards to having to go down this route ourselves in January.
Spoke to Roy Louden last week about this, basically you'll have access to Google Docs, Drive etc or Office 365 (if you have signed up for it) and web browsing.
If you are looking to replace Teacher workstations or Admin who require access to SIMS you will have to either redeploy or buy new.
I forgot to ask him about printing from Neverware.
I specifically made the point of asking who would be doing the Neverware installs - if a Capita Engineer would be available or if it would be down to the school.
Was told the each school would be given a single USB drive with the Neverware build and left to it, similar to the Windows 10 deployment..
