Currently,the only available ae mode for wide block cipher is eax combined 
with cmac. However, this mode needs two calls for a message: one call for 
enc/dec , and one call for cmac(or any other mac scheme). Furthermore, eax 
doesn't support parallel at all.
To my knowledge, the Motorist mode from keyak scheme can be an awesome 
alternative with some features listed below:
One call to the permutation f
Can be applied to any fixed-length permutation f
In-place encryption and decryption 
and more...
Any interest?
