HOLY COW, this program is amazing!
I don't have a router, just a DHCP-enabled cable modem, and a unmanaged switch on my network... All the pc's get their own IP from the cable provider, I pay for 5.
Short of adding a router I didn't think this was possible, to share files locally in my ethernet environment. Tversity proves me wrong, it works like a charm, no codec issues, no probs... I twiddled some settings, but that was just based on my own configuration here locally.. V. nicely done application.
