[PWOT] Re: l2vpn work split

Tom,
I'd like to take a stab at this, I'm certain Scott

PWE3 will deal with standardization of pseduo wire (e.g., FR, 
ATM) functionality over IP|L2TP|MPLS.  PPVPNs, intuitively, 
deals with grouping of "technology sets" to document specific 
"VPN services offerings".  

Though there's certainly less obvious overlap, the basic idea
is that some of these "technology subsets" of the PPVPN work 
will be specified in PWE3.  

Likewise, simply because someone is employing a pseudo wire 
technology, this doesn't necessarily imply that the VPN 
acronym need be present.  That is, FR or ATM transport (i.e., 
the carriage bits, not "Layer 4") itself doesn't necessarily 
imply VPN.

A charter should be posted no later than Friday, hopefully,
it will help to clarify things.
