"That's the biggest reason I think big money would be apprehensive."
Who are you talking about? Do you communicate with them? 
No, Nasa, but having worked in the FM industry I think I know enough about the key drivers that major funds look for before investing their wholesale and retail client's money. I'll be surprised to see any funds stepping-in to MRF until they're confident that there's a near-term market for the end product and that there will be sufficient cash flows.
Anyway, you don't have to agree on the timeframes with all of this but at least we've established this morning that there's no current graphene end users in the world yet and people researching can make an informed decision.
Cheers
