I want to use RS-485 interfaces for my latest home automation design.  (I
think I do, at least.)  Currently I'm in need of interface chips.  I hope
to keep things simple, and wouldn't mind spending a couple extra dollars
to save assembly/design time.  If there's a simple +5V only RS-485
transceiver chip available, I'd appreciate a pointer to it.

I'm planning on running around 4800 baud.  Can I run power, send and
receive on pairs of twisted wire without much interference (to the network
and to appliances).  Also, how many transceivers can I put on a line?  I
was once told that the limit is 31.

We're planning to close on a house in April, so I'm past the "just
thinking" stage.  I'm getting a bit anxious.  Any help will be greatly
appreciated!
