[ILUG] ppp configs

I think I asked this before, but I didn't find an answer.

What's the deal with having multiple dial-up accounts? So far as I
can see, Linux perpetuates the same gaffe that Windows DUN does, in
that each supposed config (ppp0, ppp1, ppp2, etc) is expected to be
for a host in the same domain and sharing the same DNS entries,
regardless of who the connection is to.

What's more, when I click on ppp1 in usernet (ppp1 is set for
Oceanfree), it dials and connects OK, but /var/log/messages says it's
using the protocol for ppp0 (set for TINET: still works, so it may
just be a reporting bug). But where can I tell it to use Ocean's DNS
when I'm connected to ocean (and presuambly reset my domain to
.oceanfree.net and my hostname to whatever DHCP specifies); and to
tell it to use TINET's DNS when I'm dialled into TINET (and reset
domain and hostname ditto).

To compound the problem, it's a laptop with an Ethernet card, so I use
the 10/100 port both on my home network and in the office: both of
these need different domain, different hostnames, and different DNS.

I asked a friend of a friend who is somewhere in the upper reaches of
the Red Hat stratosphere and he said to use different profiles. That's
a steamhammer to crack a nut: everything else on the machine would be
identical except for the DNS/host/domain related to each ppp or
adapter setting.

Linux is supposed to be better than Windows, right? (Well, of course
it is, that's why I use it...) But surely there are other people in
the world who make multiple different IP connections...
