That said, this was a special nonprofit project put out by Dwolla and Stripe, so I'm not sure if the "guest" checkout feature is available for us common folk. If that's the case, as t0 mentions, the transfer/verification process takes quite awhile.
We're using it where a client requests to pay via cheque. Assumption here is they don't to provide credit/debit card details and frankly I don't mind given the fees Dwolla charge (25c vs. 3%).
Just over 50% of our clients have chosen Dwolla when originally they wanted to pay via cheque to date.
Unless the user already has an account with Dwolla, it takes several days to verify bank information and make a transfer. The same applies if you're accepting Bitcoin. Paypal or credit cards are almost always the best option, simply due to the instant transaction time.
