Eh?  Access has replication built in.  Granted it likely isn't a
robust or feature rich but it does exist.   How is SQL Server
replication superior?   And is it worth the extra time and effort?

If the data you want to update is additions to the
database (new contacts new companies new projects new
quotes) then this can be done simply by email.

I operate a similar system for my company where each
laptop has a blank "updates" database in addition to
the "copy" of the office database.

Then, each time an addition is made to a table (Each
record should be set to have a key and this should be
generated randomly to ensure that each addition is not
confused), the daabase runs a "make table" query that
makes a table in the updates database containing only the
new record.  This table is emailed to the office
whereupon it can simply be appended to the corresponding
table in the "master database".

i have further enhanced our system to include the append
queries in the updates database (so that the office
receives an application that they open and press the
correct button to make the update) and at the sender's
end the table is automatically deleted after sending.

If all parties email the update to all others at the same
time as sending to head office then information can
be "shared".

A harder task is to make this system work for amendments
(i.e. changes to records).  If you can accept that
the "update" is always superior to the existing record
(i.e. the senders copy does not conflict with the
recipient's) you can add the functionality of sending the
update in the same way but if the recipient already has
that record ID, it automatically deletes it and then
appends the update.

I know this sounds complicated but it's quite simple once
you take a look more closely (I can send u my code if you
desire).

the belt and braces solution (if i am not mistaken) is to
purchase office developer edition that allows database
replication over the internet, or you could create
perhaps a front/back end database over a virtual private
network.  I suspect with 6 laptops you will be looking
like me at a more economic solution!

Hope this helps
