How about creating a new "super-small" board size for people who use RHP on PDAs & SmartPhones.
The only web browser I know of for SmartPhones that can reduce screen size enough to display the board properly is Thunderhawk.
Problem is, it's really expensive.
Neither Internet Pocket Explorer nor Mobile Opera will scale down enough.
These devices are becoming much more widespread, and present a great way to access RHP, especially when away from home.
