My company has a POS system that we are updating. Currently, we have two
Openserver machines acting as cash registers and one machine that interfaces
to our gas pumps and our corporate office via dialup. The machines are a
mix of 5.0.5 and 5.0.6.

Right now the machines are basically stand alone in regards to the
transaction and price files. We are want to make our gas interface machine
a file server (it doesn't have nearly as much activity as the registers).
Basically we want the registers to write all transaction information to the
file server and get all pricing information off of the file server. I know
how to do this with NFS, but I am wondering if the are some other better
options. For example, is there something with less overhead, more
reliability, etc, or is NFS the perfect way to go?

Security is not a big issue. The only outside access to the system is via
dial up and the number is not published anywhere. Also, the only access the
user's have to our system inside the store is with a touch screen. The only
other input devices available are the UPC scanner or credit card/check
reader.

The network is a 10mb/s network. I would like to avoid replacing the
network hardware if possible. With only two clients, it shouldn't be very
busy, plus none of our store layouts would allow anymore registers, save one
that would allow 4. If that changed, it would be a new installation with
new hardware.

BTW, there will be built in fail safe measures to write locally if the
network failed for some reason.

Any ideas, comments, or concerns, not related to porting to linux because
"SCO sucks" would be greatly appreciated. The linux port is coming but that
is a separate project.

Thanks,
Justin
