M&A candidates - and how much is enough

TPG, Optus and Telstra ruled out as it is unlikely ACCC will allow.

The remaining logical candidates could be

1. AussieBroadband
2.Superloop (at 2 becuase they recently bought Exetel)
3. M2 (Vocus) though wildcard with executive bad blood
4. Who else remains.
5. Who are the others?

Basically ruling out a new foriegn player (with NBN it is unlikely an enticing market)
