VCs that are invested into BitCoin-related startups and in BitCoin itself actively are looking for ways to assist in supporting the full node network. For example, one of the primary goals of 21 Inc. is to increase the number of nodes (pre-installed into their products) globally. That company received $116M in funding.
If SpreadCoin were to assist BitCoin as a 2nd tier network, I don't see why SPR couldn't have a marketcap valuation of at least in the 8 figures.
I have been intrigued for about a year now that ServiceNodes are individual business entities.
You get some coins, you pay for monthly hosting, you manage the service, you choose which products you want to host, you get paid for your services.
In any other walk of life, that is a business.
There is no reason why you couldn't set-up a company structure around running a service node in order to benefit from the various tax incentives from running a business entity.
The issue - we will have IP checks and balances around centralisation of nodes; so while you could throw-up lots of nodes around the world as a single entity, which could posse a problem that is faced by mining, IP checks make it tricky and potential counter measure could make it a risk. This is why the white paper talks about small profits and not allowing nodes to earn big profits - but this is an issue yet to be fully addressed.
I suppose that this is the counter to setting up nodes as business entities, when just considering Bitcoin full nodes. The effort vs. reward is not there on a mass scale unless you run all the nodes in the network or the price gets to very high levels. But then, trying to control the node network is something that can be done today, that's how AML compliance is starting to pan out.
