Been a long time coming but, today I officially updated all of the Hobbyduino boards to Optiboot 4.4 (same bootloader that is on the Uno).  I’ll follow this post up shortly with a tutorial on how I did it.  For those that cannot wait, you can take a look at my introduction for the Hobbyduino Mini Bootloader ISP Shield.  The process to load Optiboot is pretty much the same as that for the Arduino Duemilanove w/ ATmega 328 bootloader except the board type is now ‘Arduino Uno’.
