sql server replication : Copy of Subscriber Database

We have Wan Cenario with about 180 site. We need replicate many tables, that
grow up the subscriber database to almost 20 Gb. I intend to make
Transacional Replication.
All test with pull subscriber is ok, but without @independent_agent,
@immediate_sync,@allow_subscription_copy options , i mean, these options are
"false".
The option "ALLOW NEW SUBSCRIPTIO TO BE CREATED BY ATTACHING A COPY OF
SUBSCRIPTION DATABASE", need these options to be "true", but in that way, the
initilialize and syncronism failed.

Please, if anyone know any articles or "the stones' way", please , answer me.

the subscription copy method only works for subscription databases less than
2 Gigs.

What do you sugest? Many site have 128 Kbps link, but with less bandwith in
fact. When we make all initialize (snapshot), many tables don´t complete it.
There are 180 sites and only few sites can get all initialize(snapshot) and
syncronism work's ok , cause these ok sites have about 256 Kbps link or more.

The resume the cenario is:
1 database with 60 tables located in Central
1 table is a big one - 5.000.000 rows, 617 Mb of data - this table is need
for filter
half tables(30) direct replication(all rows)
half tables(30) need horizontal filter using the big one table
These sites belong's a child Domain AD for Central, with one site for each
one - replication AD in tree hour
In fact, The DB size is about 10 Gb.

Transacional Replication of SQL Server 2000 will work in that way (Syncrom
data replicate) or we´ll need other solution?

Can you send the snapshots to them on a cd? When they pull there is an
option to use an alternate snapshot location.

You might also want to try ftp with compressed snapshots. With databases
this big deploying snapshots over low bandwidth unstable links is always
problematic.
