Streaming is always a preferred way of doing things, as is dividing work into regions. If you have the source data in a database then you can easily divide the data into a rectangular grid and process each cell in the grid separately and then do some seeming on the edges as post processing. I've done this a lot recently and used this to distribute the process across many machines.
The other option with a database data set is that you put the TIN code behind a web service and the user's GUI would pass in the Bounding Box for the area to triangulate and the service would build the TIN just for that region. So this is on-demand chunking of data. You'd probably need to add in some limits to the size of the BBOX though. Just from my quick read of the streaming approach it looks like it's still using the same algorithm to generate the triangles themselves as it is just doing it within a specified region. So if we start with producing a robust TIN generator then we can plug that into any of the other approaches.
