"v1.2 will be the next release after v1.1. v2.0 will provide a rewritten master process and config handling framework, which makes it a lot easier to implement several other features. Many people also want to use configuration that currently isn't possible, but will be easy to support using v2.0 (e.g. different auth lookups or SSL certs based on local/remote IP or protocol)." Well, seems it's already thought up ;) For now, I'll run seperate processes, either as seperate Xen domains, or on the same server Thanks all!
