Yes there is. There's a pppd plugin which comes with the openl2tp 
project, http://sf.net/projects/openl2tp. OpenL2TP supports both LAC and 
LNS operation. A patch is also available to allow this driver to be used 
with another L2TP implementation, l2tpd.

Yes. :) The plan is to submit the pppol2tp plugin for pppd for inclusion 
in the pppd distro after the kernel driver is integrated.
