Yes, IP "Protocol" 115. Typo.

Or be tempted to implement IPv6 for PPP on Windows XP and sell it (or offer it 
as shareware) for ~$9.95 for a while... Until Longhorn comes out, you might make 
a little money on the side... (whether L2TP is used for v6tc or not).

In the end, a lot of implementations may actually be CPEs rather than hosts, in 
which case having the linux implementation helps.
