The countdown now begins.  With DADT repealed, by this coming summer, there will be at least one suit pending in federal court where a gay servicemember (doesn't matter, male or female) that was married in a state that has legalized gay marriage will have joined the service and been denied either "with dependent" pay or housing. 

The regulations mention nothing at all about the spouse needing to be of the opposite sex.  So the suit will be legitimate, and the federal courts will require that the services provide the same benefits for the gay couple that they provide for married couples who are not gay.  This is a very good backdoor way to get the federal government to recognize gay marriage, and there won't be a thing anyone can do about it. 

The law of unintended consequences will strike the 111th Congress once again.
