I am not a developer- far far from it. We are in the same group, you and I.
Just my thoughts, but I think the purpose right now
of the LiveCD is primarily to make sure it boots to a usable desktop.
Our definitions of a usable
desktop varies, but I think they (the developers) are focusing first on the basic boot-up procedures across different hardware.
You might want to try 'portable applications', as they don't require installation. A portable application is the normal application, but modified to 'just run' without installing. A typical use for a portable app would be to put a 'portable version of Firefox' on a thumbdrive so you can use your own web browser on any machine you plug the thumbdrive in to. Or a 'portable version' of a text editor, etc.
Currently, I use a virtual computer to test. If you have a computer with enough RAM and CPU speed, you can use the same software to try out ReactOS without any fear of harming your real machine. You can also save CDs/DVDs by using the ISO file in the virtual computer as if it was a real CD/DVD in the drive - negating the need to 'burn' the disks before use.
I'm sorry if you already know these things- including it in case you (or someone else) doesn't already know.
And in case you are interested in putting some effort into making a LiveCD-
You can slipstream files into ReactOS and create your own LiveCD with what ever you want on it. It does take work, especially if you haven't done anything similar. I have yet to slipstream files into ReactOS...
Let me know how it turns out if you try portable versions of programs- I've stuck to my BootCD installation in my VM (virtual machine). I setup a small harddrive for it and it seems great. 2Gig partition for ReactOS. And the partition is NOT real- just another 'virtual' device- no fear ReactOS will mess with my real OS.
Any questions, just ask!
