Billed as a "next-generation" Dock Connector extension cable, CableJive's dockXtender ($26-$32) is a two- or six-foot cord capable of letting the iPad dock with pre-iPad audio systems, and extending the length of any existing Dock Connector cable or accessory. With a narrow male Dock Connector plug at one end, dockXtender fits into small holes in cases; the female Dock Connector plug should have no issue fitting into any Universal Dock.
