Replication / Offline Template instantiation / Sequences

Folks,

I'm in the middle of a project where some 150 laptops need to be replicated from a main server. The C/S app that runs off the main server is kind of duplicated to the laptops (less functionality on laptop than in C/S env.).
No problem so far.

Because of the sheer amount of portable clients, and the fact hortizontal partitioning is used, rollout should be using a template, preferably instantiated offline (online is an option).

Problem is, that there are a couple of sequences (sequences cannot be replicated!), for which the following resolution was inveted: every client sequence gets upped by 200 (main server too!), but gets it's own unique starting point. So: client 1 starts at 120001, client 2 starts at 120002, 3 at 120003, etc, etc.

Question is: how do I code that into a template? How do I know which clients are actually rolled out when rolling out (e.g. laptop # 200 is the 7th client being rolled out, so the sequence would have to start at 120007)

All ideas welcome (including other sequence problem resolvers, as long as I do not have to change from number to varchar2)
