In May Kvant guys did a nice laser show in Ha Long Bay in Vietnam. You can check their video here:
They have used 6 laser systems controlled over Fiesta.NET - that's not very complicated. But the interesting part was using all the lasers and DMX devices wirelssly over Wi-Fi antennas. See the installation scheme on following picture:
All 6 lasers were controlled over one(!) wireless line (two wireless antennas). Four other Wi-Fi lines were used to control DMX lightning placed on every one of the four islands in the area. One island was also used as a projection screen for two middle laser systems.
"We had some initial problems using more wireless antenas at once", said Martin Vozar, main laser show designer from Kvant. "But after we've defined separate lines for every wireless antenna, we were able to control 6 independent full color laser systems over one Wi-Fi antenna using 6 Fiesta.NET devices."
