Why not just try to make your own with the mastering, or by doing it with morphix... it seems like it would suit your needs of only the programs you want, and alievate the need to have large amounts of ram in order to load the ISO to so that a new cd must be loaded.
You would also have more issues with noobies who can't figure out what is going on. When i give a CD to my friend, who has no clue, he is barely able to realise that he can do stuff by hitting F2.

Sorry if I sounded like an Arse, I truly didn't mean to, and I am too tired to be able to tell.
