i will tell you what we do here:

We have a disk area on a file server call /home/AIPS which is 
automounted on all computers which might want to run aips.  For 
simplicity I will assume that both machines are Linux (it gets messier 
to support > 1 architecture but that can be done).

/home/AIPS is the $AIPS_ROOT - its file HOSTS.LIST has many lines such as

+  PEGASUS    LINUX   COAOARN  NONE        Pentium 4 1300MHz Greg
+  PENNS      LINUX   COAOARN  NONE        P-IV 1.4GHz, George
+  PHECDA     LINUX   COAOARN  NONE        Dual Xeon 1.8GHz, Public
+  PRIMATE    LINUX   COAOARN  NONE        Pentium 500 MHz, Eric Greisen
+  PYANFAR    LINUX   COAOARN  NONE        Pentium 4 3GHz, Jean Eilek

listing all the computers that will run AIPS off of this central 
installation.

The area $AIPS_ROOT/DA00 contains directories which are normally soft 
links such as

/home/pegasus/AIPS/PEGASUS  ->  PEGASUS
/home/penns/AIPS/PENNS      ->  PENNS
/home/phecda/AIPS/PHECDA    ->  PHECDA

etc.  Note that it is important to have the actual files on the host 
that uses them.  These are the areas that are set up by FILAIP run on 
each machine or the proc SYSSETUP <host> for a new <host>.

The data areas are set up in a variety of ways (we use a global map but 
there are easier ways):  in file $AIPS_ROOT/DA00/DADEVS.LIST we list e.g.
-  /DATA/PEGASUS_1
-  /DATA/PEGASUS_2
-  /DATA/PENNS_1
-  /DATA/PENNS_2
-  /DATA/PENNS_3
-  /DATA/PENNS_4
-  /DATA/PHECDA_1
-  /DATA/PHECDA_2
-  /DATA/PILABO_1
-  /DATA/PILABO_2
-  /DATA/PILABO_3
-  /DATA/PILABO_4
-  /DATA/PILABO_5
-  /DATA/PILABO_6
-  /DATA/PRIMATE_1
-  /DATA/PRIMATE_2
-  /DATA/PRIMATE_3
-  /DATA/PRIMATE_4
-  /DATA/PYANFAR_1
-  /DATA/PYANFAR_2
-  /DATA/PYANFAR_3
-  /DATA/PYANFAR_4
-  /DATA/PYANFAR_5
-  /DATA/PYANFAR_6
-  /DATA/PYANFAR_7

An easier way would be to set up soft links in

$AIPS_ROOT/DATA/

as, e.g.

/home/pegasus/AIPS/PEGASUS_1/     -> PEGASUS_1
/home/pegasus2/AIPS/PEGASUS_2/    -> PEGASUS_2

etc

The file $AIPS_ROOT/DA00/NETSP also needs an entry for each data area:

Note that this file can be used to restrict access to specific user 
numbers (all 0's means no restriction)

Finally, we make all areas owned by groups "aipsuser" and put everyone 
who wants to use aips in a secondary aipsuser group.

Much of this information and more may be found on the aips manager FAQ 
from our web site
