Sosh, in your Server Only post, you mentioned that there were a few concrete objects being referenced in our code. Do you remember what they are and if you have time could you make a list of them please so that I can work on abstracting them out of the main codebase.

Cheers

No problem, there were only a few.

WheelMUD.Core.Interfaces.ISystemHost contains method UpdateSystemHost which references the object SystemUpdateArgs.
WheelMUD.Core.Interfaces.ISubSystemHost contains method UpdateSubSystemHost which references the object SystemUpdateArgs.
WheelMUD.Core.Interfaces.IRoom contains method RaiseReactionEvent which references the object ScriptingCommand.

I think thats it.  Like I said, there were very few of them.  Once you've done that though, you can abstract the server from the data completely.  Just implement the interfaces in your concrete objects - but you probably already knew that .
