[Serusers] Multple SER servers on same domain

Hello Everyone, Just a new face on the mailinglist (only been lurking so far) so just a friendly hi from me to all of you. I was wondering if the following idea could be realised with the use of SER and some (advanced) routing rules. One main SER server with one or more 'slave' SER servers running at their own location with a synchronized user database, but with their own presence table. e.g. if someone on the main SER server asks for a connectiong with a user on a 'sub' ser server of the same domain, the main SER server looks up if the user is online on it's server if not it checks if the user is online on one (or more) sub servers. What i like to accomplish is multple local networks that run their own ser server and support their 'local' connections, but sometimes there is a connection available to another local network, in which case more users can be reached. so on a request and fail of the user online on the local server it would try and see if it can connect to (any) other server and if so query if the user is online there. so everyone will be user(a)domain.com but it would point to the ip of the local server. Any config examples on how to achive this if possible would really be appreciated.
