I suspect FTTN will be configured the same as FTTH in so far as all circuits 
will have dedicated CIR's.   Therefore If you are buying a 2 MB service you 
will have access to 2MB fom the node to the aggregation point.   In FTTH 
equipment you can have business customers and home customers co existing 
without either being able to interfer with the other.  The FTTH equipment I 
have looked at will not allow you to oversubscribe the bandwidth although it 
will allow you to configure burst.    The equipment also has the ability to 
have E1 cards etc.   I suspect the node stuff will to.

I don't think this will be the issue.  I see the issues as being
-  lack of competition which will mean a lack of innovation
-  A monopoly network where the network operator will be able to hold all 
resellers and customers to ransom

If you extrapolate that it will mean that the monopoly operator will have no 
need to innovate, offer updated services or technologies and the operator 
will be able to hold the countries telecommunications users to ransom.  To 
give an example it will mean that Australia will be back to the future where 
the monopoly provider which was Telstra had to be hounded to provide ADSL in 
this country and no other operator was able to deliver, because of the 
incompatibility reasons offered at the time.

I very much doubt to much thought has gone into these issues politically, 
and I doubt the "expert"  panel will have the experts or terms of reference 
necessary to consider  such issues.

We are in for a rocky ride until the government sets a policy framework in 
place that provides some investment certainty.  Given dealing with the dbcde 
/ dcita in the past I doubt they have the quality people to advise the 
government.  Put your seatbelts on

This functionality is I suspect will be built into the FTTN however 3 rd 
party operators will need to rely on the network owner / operator to install 
and configure equipment, possibly at inflated prices.

not to meantion all the dslams and investment that will be left stranded.

There may be no choice eventually

I would refer to it as a back to the future monopoly world.
