I'm looking for a solution for wireless cable replacement.

The first question is WHY ?

Is there some moving systems that can not use wire connections ?

Or does the marketing droids think that the wireless connection are
"sexy" ?

Because the customer wants it.

Basically I
would like to have some wireless technology that replaces cables from
point A to point b-z.

Sounds multidrop to me.

Pretty much though each device may communicate independent of
each other which isn't usually the way multidrop works (usually
master/slave).

I'm thinking about more than one RS232 cable and
I'll need to figure out the control mechanism for the control
pins. Anyone have any ideas? I'd be willing to build it myself so any
solutions would be of interest to me.

You should look how RS-485 multidrop networks actually works and then
apply this to the wireless networks.

I work with networks so I am familiar with multidrop (usually
SNA). I'm not sure which we I'll end up with, polling, multimaster or
IP. Since I do so much IP I learn towards that technology but that
would require a more powerful processor.
