Since WCF Facility has no docs ATM, I think creating some screencasts about it would be of great benefit to people using it (or considering using it)

With the upcoming release of 2.5, a cast detailing the top new features/changes would be cool.

create castle monorail routing screen cast that shows how you can handle multiple querystring parameter in a restful way. It should also show how to use PatternRoute.

Show the steps needed to get MonoRail to combine separate javascript files into one to improve performance by reducing http requests.

Show the basics of setting up tests within MonoRail

how to use JQuery in MonoRail.
Show some eye candy ;)

Cast about testing code interacting with Windsor.
That would be ensuring components get registered properly etc

Implementation of MVP in a winforms environment, leveraging Castle to wire it up

Show SparkView and also Brail

It would be excellent to see exactly what casts are planned/ confirmed for the future and potentially an ability to remind me [via mail] when a cast is available

Would be nice to see the difference between the various lifestyles available.

Either a single cast about the facility or to keep it short and focused three casts:
1. interface-based factories
2. delegate-based factories
3. customising factories with selectors

Show the purpose of custom helper classes. I suppose also you could show the idea of filters as well

Explain how viewcomponents can be used and created to keep views dry

Show how to configure a MonoRail application to use Windsor to create controllers and inject their dependencies.

Create a cast (or series) around DymanicProxy. Show how to set it up, use it and what it's good for.

Create a cast the shows how to configure and use the Automatic Transaction Management (ATM) facility with Windsor and ActiveRecord.

In episode 9 we saw a brief introduction to the fluent Windsor API. Create a cast that shows the power available.

Suggested by a visitor. Show how Windsor and IoC helps with testability. Show how it enables mocking of dependencies when unit testing a class.
