[horde] horde interapplication conflicts

That's the general idea, yes.

Okay.

Okay, that all looks reasonable enough.

I'm not sure what the question is here?

You mean $conf variables, not preferences, right? Right now we only really 
support loading one set of $conf variables at a time. But this is something I'm 
going to have to solve sooner or later, so count on it working.

We contributed a set of Log:: classes to Turba that log to pretty much 
anything. They should do the trick nicely.

Sure; hopefully you've gotten enough feedback by now to at least make things 
less vague. :)
