Glad you are finding success! Let me answer your questions about owserver.
Good news. owserver is very flexible.
So multiple connections to owserver: OK
owserver to owserver: OK
owserver to multiple owservers: OK
owserver to any mix of real adapters and owservers: OK
As you can see, owserver is very powerful. It allows multiple connections to
the same adapters, allows pooling adapters, and allows network separation of
adapters and clients.
I gather that you aren't going to try to talk to the raw tcp traffic directly
any more. That is wise. You won't have to worry about changes in the program
this way. Clearly, the ascii interface (OW_get("26.1212123333/temperature"))
is never going to change, but the tcp messages will probably evolve over
time.

Great! Note that this data point was probably cached, which is why you are
getting the same exact number. Try
OW_get("/uncached/26.121212333/temperature") if you want a new measurement
each time.

You can use either:
owserver -u -p 3000
owserver -u -p 3001
...
oswerver /dev/ttyS0 -s3009
owserver -s 3000 -s 3001 ... -s 3009 -p 4000
or
owserver -u1 -u2 ... -u8 /dev/ttyS0 -p 4000
The later choice uses less memory.
