Immerse Framework Alternative?

I was about to purchase Immerse Framework for my University.

Sadly it looks like they have decided to repackage it as a consumer product, presumably with no further access to the building blocks.

With that in mind, does anyone know of some alternatives? It was fully featured, which is presumably why they felt they could go fully commercial with it and close it off...

 

They went this route because they couldn't get past some bugs they had, and instead of admitting it, and providing refunds to customers, they deleted ALL references to it, and changed the website to a "new" product. Feel lucked you didn't get scammed out of hundreds of dollars
