Do you think Phobos could benefit by adding data-binding interfaces? The
purpose is to provide the infrastructure necessary so that other libraries
(GUI Toolkits, Validation, ORMs, etc) can inter-operate seamlessly.

In .NET there's a whole set of interfaces for this purpose. They don't have a
great design but the fact that they are standard makes possible to create an
object that can be bound everywhere and performs validation everywhere
(everywhere been, windows client, web application or web service).

You can see all interfaces related to data-binding here:
http://msdn.microsoft.com/en-us/library/41e17s4b.aspx

But the more used are these three:

INotifyPropertyChanged
Provides an event to notify listeners that a property has changed.

IDataErrorInfo
Provides methods that allow validating and display corresponding GUI elements
to the user.

IBindingList
Provides notification when a collection has changed (elements added/removed,
clear, update, ...)

Thanks

I like the idea..
IMHO this could be done by porting and enhancing the Mono code, use 
Stevens dcollection lib, enhance dCollection with observable containers 
and you are nearly done. Due to the Mono license a phobos independent 
project is appropriate.
my 2 cents, bjoern

Why do we need to port the Mono code? This seems quite easy to implement.
