Redmine

What I'd like to achieve is to split redmine and svn, so redmine users it's own redmine.example.net host and svn uses different svn.example.net host.
I'd like to have base integration: automatic repository creation, fetching changes after commits and access to repositories based on redmine's database.
Daily/hourly cron job is enough for me.

I've all of this on one server and I really want use dedicated server for svn with same integration features as for placing redmine and svn on same host.

I've read howto but it didn't help.
