No this is all talk, a fork to reallocate 80/20 would cause the coin to dump, it has been proven that moving rewards to the masternodes increases the value of the coin and the reverse decreases it.  This was made clear in Ryan's talk where in the early days of DASH Evan was boosting the allocation to mnodes from which Tok and AFBTC greatly benefited from as it caused the price to pump each time.  Recently, we increased the ratio once more and just the news that we were doing so boosted the price from $65 to $93 in a matter of weeks and we we are still 5 days out from the first boost. 

For your shared node, look into crowdnode.io.  I'm sorry, but shared nodes are stupid and lowering the amount needed for a mnode significantly will never happen, we don't need minnows running mnodes, those are for people with serious money to invest, because it is a high risk venture and requires a lot of your attention, the last thing DASH needs is an army of minnows not giving a poop about the DAO because their investment in it is so low.

Also, remember the purpose of a mnode it is to thwat sybil attacks and provide just enough nodes to secure the network and run the services on layer2 without so many that it would delay the propagation of TXes.  5000 nodes is about right, probably with a factor of 2 lee way either side.
