You *CAN* just send VGA over CAT cable in the same way as you can send
Composite Video ver CAT5 cable without any form of balancing whatsoever.
What you CANT do it maintain the quality or send it any distance without
serious degradation and susceptability to interference.

Whilst twisted pair has an almost magical immunity to interference it ONLY
applies to balanced signals and that page describes sending ordinary
unbalanced signals.

It is a cheap method though .... but then you get what you pay for :-)

Keith
