In this project in 2010, we are blessed with the chance to work in a Ruby on Rails project from a UK company that features many interesting technologies.

One is VoIP. We first tried using Lypp, but too many bugs and it's very unstable, and fortunately there is another better service for VoIP calling, which is Ribbit. One of its interesting features is to let two users connect on their landline (or mobile) phones by clicking on a button in our website.

Two is Webcam. We know Flashcoms, but we use Red5 in this project, well, because it's free. Red5 server will enable users to communicate via their video cameras within our website.

Three is Worldpay. We have been looking for a payment gateway that supports UK merchants, that enable us to store users credit card information in the gateway to be charged at later time. First it looks like PaymentExpress is the choice, but our client needs to set up a merchant account, which is difficult to approve (he said his business must have been trading successfully for 6 months). And even the approval process is gonna take weeks if not months to set up.

So Worldpay is the choice, although it has worse API guidelines and interface compared to PayPal, it turns out it's pretty easy to set up. We can now store user's credit card information safely on Worldpay to be charged later.
