After one hole day of testing :)

The single master -> single slave was ok.

But, what I need to implement is this.

I have 15 databases at 15 points, all connected to internet, and 
interconected using openvpn.

Each point of sale have its own database different from each other, this 
was tougth from design, that it could be easier to replicate N 
differents database than N diferent tables.

What I need, is to replicate, all 15 databases to a single server, in 
that way, I can consolidate all information.

My concern is about the use of slon.. since I need slon running at the 
master and slave, I belive, that only once instance of slon must existis 
per box... so, how do I setup 15 slon at the slave box?

Thanks..

P.D. Do you have an irc channel?
