This has been a concern by the Singapore iDA, where they desire that the 
barrier to RSP entry be extremely low (to the 'almost non-existent' 
point).  The variety of required services by the OpCo is supposed to 
reduce this.

Of course, many existing Australian ISPs have the BRAS/BNG 
infrastructure anyway, so a certain amount of re-use will be possible.
