For my house:
1. Double hung
2. Double
3. Don't generally keep many (if any) windows open; house has central air
4. Sure, that would be cool.

For my dorm room:
1. Double hung
2. Double
3. I only have three windows to close when it rains, but they get stuck opening/closing to it can take up to 10 minutes to close the three of them. We aren't too happy about this because our beds are under the windows, and in a downpour that means soggy sheets.
4. Again, that would be pretty cool, especially if it would save me from wrestling with the windows.
