2D cameras to 3D monitor

[Monthlymusic]

Hi all, I'm building up a a stereoscopic vision system but I'm new to this world so I need some advice.
What I'm thinking of is to use a couple of cameras with S-video/USB output, connect them to a PC, use Stereoscopic Multiplexer software to combine the double stream in a side by side format and view it on a 3D monitor through a DVI connector (I've got a Panasonic EJ-MDA32).
But..
I've recently discovered the term "genlocking", and unfortunately Stereoscopic Multiplexer does not replace genlocking or other means of hardware synchronization. It searches for left and right frames with minimum time offset, but cannot eliminate the remaining mis-sync.
For DV-Camcorders featuring a LANC port (Sony, Canon), dual camera remote controls are the easiest way to obtain almost perfect synchronization, but those devices are expensive and bulky.
Can you help me with a cheap solution?
What about SoftGenLock for Linux OS?

Thanks.
