PayBee is a BitPay like payment processor. It will use Monero and Bitcoin as "default" currencies as far as I know.
Fluffypony explanation of "what is Paybee" is as follows:
It's a payment gateway I've been developing along with a few partners. We had to deal with a few false starts and issues along the way, but it's (finally) getting close-ish to release.
That is really awesome. I like it that it supports both Bitcoin and Monero, so the vendor does not need to implement different payment processors for each (relevant) currency.
Nowadays it is a mess with all the payment methods: paypal, credit card, wire, apple pay, amazon points and I don't know what. They all require their own portal. Things like this make me realize (again) how important of a role digital currencies are going to play on the internet.
