... and this leads me to wonder....
What is the significance of the 'delete ALL' line referred to? 

I've got a dozen or so STATIC routes pointing between a pair of local
ethernets (They're static because they're in different networks and don't
EVEN ask about the routing protocols on the local side ;-).  I have NO
default route when ppp is down.  Gateway-ing is on in the kernel so I can
route between locally-connected nets.

As a result, I've not used the 'delete ALL' directive in ppp.linkup, but I do
use the add 0 0 HISADDR.  This works quite well as long as I start ppp from
the command line.  But dial-on-demand doesn't work as seamlessly as it
should.  If I add the 'delete ALL' line, would this nuke the local static
routes I've so carefully crafted?  I suspect it would.

In short, what I'm asking is:  How can one get iij-ppp to 
 - dial on demand
 - link up serially between "unknown-in-advance" IP's
 - Add an appropriate gateway to the ISP
 - Preserve existing routing table information on the local side
(It's the last bullet that has me stumped.)
