Barriers to entry take many forms. You are certainly correct that a couple programmers could, in theory, sit down and create their own own online bridge site. However, this is VERY different from establishing a viable competitive server.
There is a very basic concept in business known as a network effect. A network effect occurs when the "value" of a system is a geometric function of the number of users. The best known example of this "Metcalf's Law" which states that the value of a computer network is proportional the square of the number of nodes. While this might sound very ivory tower, it actually has quite a lot of explanatory power: 15 years ago, computer networking was characterized by a large number of private networks (AOL, Compuserve, Genie, MSN, The_Well, any number of BBS, ...). Over time, all of these networks were subsumed into this wonderful Internet that we all know and love. The reasons behind this had nothing to do with the management experitise of Bill Gates or Steve Case or whomever. Rather, its a simple fact of life that one network with 100 users is many times more useful than two networks each containing 50 users. There is a lot of business literature out there which studies network effects and tries to predict how the market will consolidate.
I'd argue that Online Bridge is an example of a market which is likely to be dominated by network effects.
1. The ability of players to find games is a function of the size of the user base. In turn, this creates feedback loops benefitting large sites.
2. Third party application developers focus on the largest market segments, creating an additional feedback loop
It is certainly possible to markets to tip. As you yourself note, BBO was able to displace an entrenched competitor. However, it should be noted that BBO penetrated the market by leveraging a radically different business model (free pricing as opposed to $100 - $200 annual usage fees). More significantly, OKB's management team seemed to lose interest in improving the site. From my perspective, they went into a mode in which that were trying to milk the user base for as much money as possible before exiting the business.
