Yes, the cost of publishing results, as well as review, editing, etc, should be incorporated into the research budget (researchers can of course choose other means of sharing their findings than through publication). In an open access model, the publishing costs are offset by money saved in not paying for access to other articles the research project needs. I would hope that opting out means that projects have to pay fees on articles they'd otherwise get for free through this agreement, rather than riding on everyone else doing their bit.

One would imagine the fee schedule is set in the agreement UCB reached with Springer (presumably the agreement will be published at some point...)
