1.      MOAS isn't necessarily a 'problem'; it's fairly common, these days, and has been for quite some time.  The 
actual problem is the inability to determine when it's intentional and not evil, vs. unintentional or intentional and 
evil.

2.      There's already a fair body of work on this topic, as a Web search for "multiple origin as" reveals.  Check the 
NANOG archives for Lixia's preso, among others.
