All of the SOHO router/NAT devices they sell at Harvey, Dick Smith, 
Harris Tech. ect can lease IPs to wireless clients. My IPcop 
firewall/router/NAT server uses DHCP3-server to lease IPs to wireless 
clients. I haven't tried PXE booting a wireless client but AFAIK it's 
possible, you'll just need to find a wireless NIC that supports PXE. Or 
you could build a boot cd/floppy with a pxe enabled GRUB.

Knoppix allows you to runup the livecd and setup a LTSP environment from 
within the desktop. I'd have a look at the pxelinux config file that 
Knoppix creates to get some pointers. You may be able to set the rootfs 
to be a NFS mount but that option needs to be compiled into the kernel. 
Appending "root=/dev/nfs nfsroot=" to the 
pxelinux prompt should set the root filesystem to be on the NFS server Alternatively you could include it in the pxelinux config 
file on the APPEND line for the kernel you are booting.
