<div class="moz-cite-prefix">Its true that at present congestion is
going to be difficult to achieve ;-><br>
They are also generally running a 20-25 way split (with a max of
32 or so as you say) so even with all users on 100mbps you would
be having a bad time to hit the cap on 2.5gbps.<br>
<br>
But I *presume* that given they are offering gbit services (even
if none are available through RSP's) that nbnco would have the
back end systems to manage congestion in the wild.<br>

fear we're straying wildly off-topic, but aren't they
doing a 32-way split on 2.5Gbps of bandwidth ? Even if
all of your 15 users are on 100Mbps plans (the max
available right now) then they wouldn't be able to
saturate the 2.5gbps bandwidth available (ie. 15 * 100
= 1.5gbps) ?</span></div>
