Generally in order of priority:

    * Prepared Statement with binding (easy!),
	* Windows and Mac compatability/portability,
	* Auto-documentation,
	* Convenience constructors,
		(Might wait for constructor delegation in G++ and MSVC)
	* Source control,
	* Add PostgreSQL interface,
	* Features:
		- Parameter binding,
		- Column metadata retrieval,
		? Additional type handling ?
		? Wide character support ?
		? Prepared statements ?
	* .NET API
