Is there a reason why ms-access was added as a tag here? It seems to me that the question has nothing but the most trivial relevance to Access, since once you're working with .NET, Access is completely out of the picture.

ASP.Net with it's code behind is *almost* MVC - but not - the one big thing that makes it not is that the codebehinds are tied directly to the aspx's - which is a big component of MVC. If you are thinking of the codebehinds as the controller - the should be completely decoupled from the view. The new .NET MVC rounds ... |

App Domains are great for application stability.
By having your application consist of a central process, which then spawns out "features" in separate appdomains, you can can prevent a global crash should one of them misbehave.

If you are using the .NET Framework 3.0 or above, I would use WCF. Using WCF, you can use different bindings depeneding on the trade-off between performance/interop/etc. that you need.

`std::list<int>` is slightly nicer, IMO. Note that this would not require an extra copy of the data in the list, as it's only pointers being copied.
