Fine. I used it like that for several years, both modem and ISDN. In
fact the reason I ended taking over diald from Eris was because there
were some things that needed to change to handle double ended demand
dialling.

In particular, pay attention to the died-retry-count option. If both
ends can demand dial you want to set this to 0 so that the link is
_only_ brought up if there is traffic. The default is 1, which tells
diald to assume that the other end is dumb and that if the link goes
down while diald has active connections it must bring it straight
back up again (even if no packets are currently flowing) because the
other end won't even if it has packets to send. The default is fine
for ISP type links but if both ends demand dial it leads to links
that bounce up and down and up and down and ...
