Hmm... people, you have to be considered with these shows. While there are some people at the show, there are still people in other shows and they need to arrive. Also, remember that while all of these people is standing out chatting, backstage is crazy with hair/make up and that takes time.
So yeah, at least be grateful to have the inside scoop of a fashion show in real time, the waiting is worth it.
About the milkmade streaming, ilaughead pointed out in the Spring Summer 2011 Runway Music thread that the music according to Showstudio at Wang was Die Antwoord while at Altuzarra was LCD Soundsystem's "I Can Change" - so there goes my suspicion about if the real soundtracks are being played at the live streamings.
