I just started a thread in the forum about this, but please see:
http://lufs.sf.net
It is a kernel module that does basically the same thing as kio_fish, but on a system-wide level. You can use it to mount ssh, sftp, ftp and will soon include http and webDAV. This would allow easy access to home/work directories from within any application in Knoppix. I'm guessing you could even use this with persistent home allowing you to make your home dir a LUFS such as:
mount -t lufs none /mnt/home -o nosuid,fs=sshfs,host=MYdynamicIP.yi.org,username=m ali,fmode=444,dmode=555

That would be awesome.
So, to sum up: Please include LUFS in your new kernel for v2.
