Taking these comments into account I've decided to reduce the scope of the
project to focus solely on the network stream mixing and synchronisation
problem. I will write the code with future features such as graphics, fades
etc. in mind but by the sounds of it I won't have time to implement them
before my project deadline.

Yeh this was a pretty vague question wasn't it! I suppose this is something
I really need to wait for, and test out once I've written some of the code.
I have almost finished my initial research and should be starting to code
next week hopefully...I expect I'll be back with more specific problems
