I am curious to know if anybody out there really uses ISP-driven mandatory
VPDN's.  By that, I don't mean the client-driven PPTP/L2TP tunnel for the
roving salesmen to dial back into the office network, as I am well aware
that this is quite popular.  What I am talking about is the ISP-provided
mandatory VPDN, where the access-server is the  LAC , and there is a 3-tier
architecture between client, LAC, and  LNS.

Now that IPsec, and accompanying client software is so prevalent, it seems
to me that there is not much reason to use ISP VPDN's at all.  I understand
that there are certain advantages from a ISP VPDN that are unavailable from
a client-driven VPN.  But it seems to me, at first blush, that these
advantages do not outweigh the added cost and frustration of dealing with a
telco.

So can anyone present a case when an ISP VPDN is indeed the best solution,
better than any of the alternatives?

Note - I'm not trying to dis' anybody who really likes ISP VPDN's.  I Not at
all.  I am sure there must be some reasons for using them.   I am just
trying to gain an understanding of what those reasons might be.
