Well, there's Dove, the chocolate, and Dove, the soap. I don't think intelligent people will get confused at eat the soap or try to wash their hands with the chocolate. Let's not blow things out of proportions and comment on any name collision as something bad! Software projects come and go and Consul.io is not something that, in my view, will last forever.
Yes those are totally different. You can have a trademark of the same name for different things in different industries. This is allowable under USPTO guidance. However, these are both software, so your scenario isn't really comparable.
