The problem:

	Two Unix computers are to be installed about 5 miles apart. They
	need to have some form of high speed communication between them.
	Uucp over a high speed modem over a leased telephone line may suffice.
	I am concerned about the reliability of uucp, however.  What are my
	other options. 

Priorities:

	1) Integrity of data.
	2) Minimum maintenance.
	3) Throughput.
	4) Cost.

Thanks:

	All responses will be greatly appreciated. If I get enough 
	responses I will summarize. I also welcome any suggestions about a
	more appropriate or specific group to which this question should be
	posted.

A couple of weeks ago I posted a question about how to move files between
two Unix computers that will be about 5 miles apart. Thanks to all who 
responded. I would like to fine tune the question and summarize the responses
that I have received.

There were three suggestions that all used high speed modems. Telebit seems
to be the unquestioned modem of choice.

1) uucp
	We are very familiar with setting up and running a uucp network.
	There is no software cost and it is fairly reliable. One of
	the responses uses uucp on a 17 node network and is very happy
	with it.

2) SLIP (Serial Line IP) 
	SLIP seems to be a mature technology that allows the use of
	rlogins, ftp, and nfs. What are the problems with administering
	SLIP? Is it readily available on various Unix computers? What is
	the software cost? What kind of throughput can I expect?

3) PPP (Point to Point Protocol)
	PPP is a new technology similar to SLIP. One netter reports
	a throughput of 1.7-2.8 Kbytes/sec with FTP over Telebit T1600s
	modems at 38400k baud using V.42bis data compression. 


Thanks again for your responses.
