Thanks for the advice. I've been getting really into networked video, both for work, and out of my own interest in expanding my digital signage capabilities.
What are NDI tools? Do they come packaged with Spout? I haven't used a PC in many months now...saving up for my own machine.
I'll check out NDI Viewer and Syphon View for iPad. iOS + Syphon / Networked video sounds really appealing. No need for me to cross Spout and Syphon just yet.
