I have never used /etc/passwd users with vpopmail, but it's my
understanding that you can use them in addition to virtual
domains, so you could have both.

Sounds right to me. But I highly recommend setting up a test
box to make sure this will work ahead of time.

Yes. I think that if vchkpw is compiled with roaming user
support, any successful authentication (regardless of where the
auth info is stored) will allow that IP to relay.

I'm pretty sure your setup will work as you expect. But testing
it on a test box will tell you for sure.
Since you're running your POP server as root, you shouldn't have
any permission issues with vchkpw updating the cdb relay file.
You may need to specify the location of the tcp.smtp when
compiling vpopmail.
Good luck.
