What's the end goal here? Avoiding AoOs is nice, but is usually not an objective in itself. If you explain the task you're trying to accomplish, that might suggest more options, or limit the possibilities.
If you're a rogue attempting to get into flanking positions, Tumble or Spring Attack would probably be your best bet. Using a tower shield or a transport spell would prevent you from attacking that round, meaning you're stuck in melee range longer than necessary.
If you're a melee type looking to bypass a crunchy fighter shell to reach the soft wizardy center, all you really need is a high movement rate. Take levels in monk or barbarian.
If you yourself are the soft wizardy center, seeking to escape from melee or grapple, dimension door is your very good friend. You probably don't have levels or feats to spare on the other options, especially since this is a relatively rare occurrence.
