Thanks for that syrovi - we've been slogging like dogs, working through the upgrades; and it's nice to know we're making a difference. We have an excellent team at work who managed to complete 7 sites in 2 1/2 days in Rustenburg. We've just returned from the Welkom/Kroonstad/Bothaville area where their upgrade is almost complete.
The speed you are getting (probably more consistently than previously) is 128kbps, which is equivalent to a dual-channel ISDN connection. We have not completed the new firewall queing (?) and bursting configuration, but will be re-implimenting that within the next few weeks. The bursting will again allow for fast browsing and small downloads, but limit your larger download speed to that of your subscription. As you say - good value uncapped options are also available.
The reason why P2P was previously disallowed was that we did not yet have a solution to identify and control these connections. The good news is that now we do allow it - but these connections will be shaped, limiting your download speed on P2P. At this stage there is no shaping on P2P, but this will be implimented with the new queing and bursting setup.
So - basically the change in approach along with the upgrade is
'Allow everything and only block that that is potentially damaging' rather than
'Block everything and only allow that that you want'
