DSL Ideas and Suggestions :: Absolute SMALLEST (barebone)

I like SMALL linux distribution, it is wonderfull to have a linux distribution even on single CD such as Ubuntu, but now I can have smaller 50MB wow.

Just is it small enough ?

I have suggestion could there be a BARE BONE version, which consist nothing just the Linux OS and Fluxbox without all other applications ?

Since in fact not all using packaged application and not all people like the chosen there. Just simply a BAREBONE and HAVE an option to DOWNLOAD the rest and install it EASILY is the BEST WAY to customize yet another smallest one.

What I need is a linux OS which is :
1. Can install with easy interface
2. Can dual boot easily with XP
3. Auto detect all hardware when install
4. Start default on X window environment
5. Can connect easily with Windows Network
6. Can download and install application and update easily

The app I need just (no need in install CD, just option to download & install easily):
1. FireFox for browsing
2. GAIM for chat
3. xIRC for IRC
4. OpenOffice need only the Word, no need spreadsheet etc.

I don't need anything other than that, please could DSL build the SMALLET BAREBONE EVER ?

Thank You so much
