Current Ubuntu releases have a menu item: system/administration/startup disk creator which will allow creation of a writeable portion (a slider at the bottom of the creator window selects the size). Basically, all this slider does is to create a writeable file named casper-rw on the disk. I have seen problems with booting when making this file too large, so if you need more than a few hundred meg, you probably should partition the flash before installing. Make an install partition of 1.2G, and a big partition of ext2 for storage. Install to the 1.2G partition with a <500M writeable part, then make an ext2 filesystem on the big second partition, and label the partition casper-rw with sudo tune2fs -L casper-rw /dev/sd<your disk letter>2
Then delete the file casper-rw, and you should have a lot of writeable space. I have used this technique to even update one of these systems, but that does take up a few hundred meg of writeable space.

Can you help with this problem?
