Hey! Where do I send my money?

As far as my technically-challenged understanding goes, G0MRF's argument is very solid - it sounds bloody good and I don't understand why nobody's working on something of that sort already. I, for one, would be quite glad to make a financial contribution to such a project, and I'm sure many others would as well.

So - where's the catch? This, as I understand, is different from the recently announced AMSAT India project, and seems to me even more feasible: three cubesats...

What is holding us back? Who could take the lead?

Best.
