Wow. That sounds a lot more positive than my experience of investigating the market here (UK) - I presume this article is US focused.
Here school IT is generally centrally managed by an IT team who are not generally receptive to ad-hoc software installs. SaaS models fail due to firewalls and network access restrictions. Preferred/accepted bidder lists are rife. Teachers have NO budget for software.
I looked at selling to teachers here and decided that it was more hassle than it was worth - the market barriers to entry and borderline corruption/incompetence just made it a non-starter.
My experience of working in 3 different UK schools:
IT teams in schools are normally small, over-worked, and underpaid (as is the default in education generally). Machines tend to run from a single source image rolled out once or twice a year. The time and resources it takes to create, roll out and support departmentally-customised builds is not worth it. Software is generally dictated by overpaid IT managers who are disconnected from both the teaching staff and the IT team. It's not uncommon for tech teams to have a small percentage of the IT teaching budget rather than their own, so decisions are based on that too.
All local authority schools where I am in the UK, and local authority sites, are managed from a central IT unit. I suspect even if you got the LEA to buy your software the IT people would refuse to install it unless it says Microsoft on the box (!). Perhaps a tad cynical.
