i do not think that could work, you could probably be able to copy an install but x fails in an hdinstall if it cannot write to the root partition.
in years to come linux may be able to read and write to a cdrw in the same way as an hdd, it is probably posiible although the life of the cd might not be as long.

I have worked on CD-Writer support and I know that the CD-RW disks are made with two different materials. When you write to them it melds the materials together making it darker and putting the information on the disk. When you erase them it uses a different intensity laser to seperate the materials. Eventually after time the materials will quit combining causing the CD-RW to fail. It all depends on the brand and quality, but the average write/erase life span is around 40,000 times.
In a nutshell that's CD-RW techonology. The result is if you want to use them as hard drives you will be out of luck until the techonology gets better

In short, DSL on CD-RW works the same as DSL on CD-R (I use 80mm mini-CD-RW for testing), BUT a lot of older drives CAN'T READ CD-RW. If the drive can read a CD-RW, and it will boot off a CD-R, then yes, it will boot off a CD-RW. But just be aware that many OLD drives won't read CD-RW - my P233 laptop, for instance, can't read them (and I've tried under both linux and windows).

So I create a custom MyDSL disc image, test it on my newer systems using a CD-RW, which I can erase and re-write if something's not quite right yet, then, once I have a "good" version with everything set up how I want it, I can burn it to a mini-CD-R, without wasting one.
ie. use CD-RW for testing, then when it's right, burn a "permanent" copy

I think he means like using the R/W function of the CD-RW to actuvely store information on the CD, which I do beleive is impossible.

this was what i was lookin for.

essentially i wanted to know if i could install my own programs and such from one computer, then take the cd over to another computer and have it still boot.
this would allow me to create my own customized livecd with the apps that i want.

guess i will have to find another solution.

If all you want to do is add apps, you can remaster the iso very simply. You can even do this in windoze if you please. That is how I make my custom cd's (I can add Gaim, XMMS, GIMP, and OpenOffice, as a few examples). In case you want to follow my method, I use WinISO to customize the iso, but there is other software available.
There are ways to get even higher levels of customization.
Here's a HowTo on remastering.

edit:
Check out the repository for the entire list of programs that can be added directly to the cd.
