Analyzing the Sep & May Telkom statements re. their 'triple play pilot' in ITWeb, several comments stand out ...
... a new broadband service called triple play, which includes Internet, music and video-on-demand.
So VoIP or telephone calls are not part of the 'triple'
... with the aim to offer DVD-quality broadcasts, video and music on demand, downloaded from a content server.
So its content on demand, theyre not trying to replace the DSTV service (i.e. live TV channels)
... both services will be through the same twisted pair copper cable.
So there will be no seperate line for the service
... will be an add-on service, so the standard bandwidth cap for downloading will not apply
This sounds like seperate login accounts for 'triple play' and standard 3Gig cap Internet access
My guesstimate of how this service will look is ... they're gonna give you some sort of set-top-box/decoder with a Ethernet/PPPoE port. It will login using special ADSL account which provides access to a media vpn to connect to content servers & web + email proxy servers.
The box will be able to download music & video to be watched/listened as they comes down & possibly later for a limited time period (i.e. stored on HD). The Internet part of the 'triple play' may be some sort of rudimentary web browser & email client built into the box's interface.
Your PC will still use your normal 3Gig ADSL account for standard Internet access.
Just my speculation, but it does seem logical based on the comments above.
