So this basically allows people to purchase from websites ("checkout") and pay using their bank accounts....

But the new thing here is that this is with dwolla's low overhead costs.

So now a company can sell you something from its website with a total $0.25 overhead cost--whereas paypal will charge you like 2.9% + $0.30.

Seems like every website out there *should* want to integrate this into their site (as an alternative to paypal or credit card checkout, which also costs $$), because, if any percentage of their buyers use it, instant money gain...FWIW.
