I currently have two PPP connections that I make: one to work; and 
one to my ISP. Now, my system spends more time connected to my ISP
than to work so I initially configured it to use the hostname used
in my ISP link. I'm also running routed and have an entry in 
/etc/resolv.conf to point to my ISP's name server.

The obvious question that I'm coming to is this: is there a "good" 
or clean way to go back and forth between network identities? I'm
using user-mode ppp and have entries for work and my ISP.

I can easily enough run 'ppp {work | isp}' and connect. The real
tricky part comes in when I want to set up the network daemons on 
the fly and change things like the routing table and so on.

I realize that I could write a script to go through and make all the
changes as needed and start ppp with the proper destination. However,
before I start down that path I'd like to know if anyone else has
experienced this schizophrenic (sp) situation and how they went about
handling it.

Thanks in advance, Sybil.
