I don't think this is even possible!
to get a usb drive to boot... the partition needs to be edited and have a bootable flag. If there is no bootable flag set on the partitions, then the BIOS cannot boot from it.

doesn't look easy as pie to use to me.
-HAL
-sets partition bootable
-writes MBR to USB stick
-formats partition FAT32
-installs syslinux bootloader
i have difficulty understanding almost every sentence they say.
and u have to have the livecd for that to work.
off course, downloading just straight to the usb would be much better than having to create that cd and then get it to the usb from there.

@meganox: I will try the testing for usb-creator (did I said Kreator is a great thrash metal band).
@anyone else:
It is possible to do it, actually I let a link to a GNU/Linux distribution which can boot from USB. Try such distro is called PUD, very light and small.

Okay, as I understand it, a USB install can exist as one of the following:
1) LiveUSB - i.e. in implementation of a LiveCD, only on a USB flash drive. It is literally a LiveCD on USB, in that it does not have session persistence (won't save changes). It boots into the same image that the installer uses to install.
This part is already implemented.
2) Persistent-session installation on a USB flash drive - i.e. Ubuntu is installed on and runs from the USB flash drive, but that installation is not a "Live" image; that is, it is a normal installation, not an installer.
This part is already implemented.
What I think you're asking for is a combination of the two - that is, a persistent-session LiveUSB, in which the installer image can be updated (configuration settings, package installations, etc.).
For example, Ubuntu 8.04 LiveUSB is created, and installed on a USB flash drive. That flash drive can then be used to install Ubuntu 8.04 on other machines.
Subsequently, Ubuntu 8.04 is booted from the USB flash drive, and upgraded to 8.04.1. Thereafter, that flash drive can then be used to install Ubuntu 8.04.1 on other machines.
Is that what you're asking for?
If so, I don't know if that is possible.

Yes that is what I am asking, by example I install Ubuntu 8.04 on a flash, then I decide to install the codecs for mp3 and dvd on the flash.
When I install this flash on other machine also install the mp3 and dvd codecs.

@Faryshta:
That's a great idea, but I don't think it's possible/practical. Hopefully I'm wrong.

Again, I put an example of a distribution that does it. Here is the link... again.
ftp://mirror.nttu.edu.tw/penk/devel/pud-0.4.8.6-lxde-usb.zip
Will be great if we can find oficial torrents or oficial downloads like this ones on the page of Ubuntu.

CD is obsolete anyway. CD images are needed only for compatibility issues now (for someone with computer old enough not to be able to boot from usb drive).
IMHO, ideal way would be:
Basic package - includes image around 1 GB (to fit on average flash drive), linux and windows executables to easily put this image on desired partition and write MBR and bootloader wherever you are (customized unetbootin would be perfect).
Basic image is able to boot live with persistent (if configured so during install on usb-drive), also text-mode installer, oem tools, etc. It also has some empty ../repo folder in it's root...
This usb-drive should be enough to run and install a working system.
Additional resources:
3-4 different size repository packages. Can add more optional software to your live's repository if unzipped to usb-drive's ../repo folder. (similar in size to current dvd version and beyond...)
Old machine package - classic CD image.
The idea is to stop thinking about these obsolete pieces of metalized plastic as of basic template for system image creation.
