All that wealthy individual needs to do is open up Pool, set 0% fee, add something like merged mining, and wait for hash to come to him. ...

Isn't that effectively the GHash situation? Small number of nodes feeding large number of miners. Controls hash but not network. Or were you thinking a p2pool setup? Anyway I wanted to investigate owning network and what effect that could have.

Yes, it is. Ghas situation. Do you job, do it great, and you get ability to attack network basicly for free, or even get payed for it (GHash is making crazy amount of money). When i see how people are dreaming of other kind of attacks, it's just funny. Like anyone needs to invest into hash power....how silly is that  Cheesy

Sheeps will fill him up to 100% if needed. Buying nodes or ASIC's to do harm to network is for newbie evil doers (Like Dr. Evil asking for 1 MILION DOLLARS! https://www.youtube.com/watch?v=cKKHSAE1gIs&feature=kp for those less fortunate that have no idea what i'm talking about)

So seeing as there are only like 7771 nodes (https://getaddr.bitnodes.io/) running, couldn't a wealthy individual or company convince a large majority of people running nodes (not necessarily miners) to, say for instance, switch their node software to the one this individual sends them?

For example, let's say someone offers full node operators, $200 a month to switch over to their 'slightly modified' node software. Maybe they bill it as just a simple data aggregation thing, or something that seems more innocuous that will benefit bitcoin, maybe it's even better software.

Anyway, so once they have this control over a large number of nodes, then they can implement software changes and such that might benefit their plans or they could shut it down suddenly or do other nefarious things.

Would this have an impact on Bitcoin as a whole? How vulnerable are we to node control as opposed to hash control?
