[Geoffrey]

Well,  I assume you're probably on the right track there.  From that 
point, you might asssume that if you used the other 2 pairs in the same 
way as the first 2 are used, you'd be okay.  But then you'd probably 
have to deal with cross-talk/interference between the two different sets 
you've not, not just between rec/transmit on one 'communication link.'

I think I'll give this a spin just the same and see what happens.

Since one twisted pair is used for transmit, the other for receive, I'll 
see what happens if I use the other two pairs in the same way.
