Is there any version of Aurora protocol which works with LVDS instead of MGTs?

Hi All,
I reviewed LocalLink and Aurora protocol and it does not specifically say 
anything about RocketIO tranceivers. So I assumed that it could be 
implemented by using LVDS pins when higher speeds are not necessary. But its 
IP just works with RocketIO.
     - I am wondering if it's possible to implement it with diferrential 
pins other than RocketIO?
     - Does anybody know another protocol and interface implementable with 
LVDS, with capabilities comparable to Aurora?

Thanks
Massoud
