Stephen,

Personally, I like to mimic the namespace hierarchy of the .NET Framework. Since a significant part of the .NET learning curve includes figuring out which namespace a class belongs in, I can make developers' lives easier by imitating that.

Based on this I would put your business objects in:

CMS.AA.Business

And if you create any custom data access classes, put them in:

CMS.AA.Business.Data

And if you create any event objects, put them in:

CMS.AA.Business.Process or CMS.AA.Business.Event

I would put your Windows Forms controls in:

CMS.AA.Windows.Forms

and your Web Form controls in:

CMS.AA.Web.UI.WebControls
