	The last system like this I set-up (I now use an off-the-shelf NAT  
router) used Debian Server running on a VIA Epia ME-6000 motherboard.  
It booted off an old laptop drive and had the following interesting  
packages installed:
	* Shorewall (for "easy as falling off a log" NAT/firewalling)
	* PPPoE (WAN connection)
	* dnsmasq (for reasonably sensible simplification/integration of  
local DNS serving/proxying with DHCP serving)
	* Samba (Shared-out file-storage from there).

	I had planned to migrate over to booting off a compact flash card  
mounted in a CF<->IDE adaptor card (But I never had a good DMA- 
capable card to hand before I went another way). I'd long since  
decided the LRP distros were too dead for me to continue using.

	Can I make these two assumptions about your situation (let me know  
if I assume wrongly):
	1) You desire a floppy-based system for the write-protection ability.
	2) Your laptop can only use a floppy through a PC-Card (PCMCIA)  

	If you really want the write-protection, then perhaps a customised  
knoppix-derivative might do. Otherwise maybe you could make a small- 
enough 2.4 Gentoo setup that could fit what you want on a floppy.  
Personally, I can live with a writable root partition. Whichever way  
- I wouldn't bother with LRP any more.

	I recall there being talk of PC-Card modules for LRP stuff - but  
last time I touched one of those was in... 2002... I think?

	I had some of my home lan stuff running on an "uNSLUng" Linksys NSLU  
for a while (DNSmasq and Samba), but it wasn't stable enough.

Hope that helps,
