you do realize that this would require changing your preferences to
tell the IMAP mailbox that you don't want to connect to the remote
server right? This would be easier to do by craeting a new mailbox
type whose check routine updates the IMAP server to/from the shadow
while all other routines operate on the shadow. Even this would
require enabling/disabling the check so that while your using the
dialup it doesn't connect to the server.

You know this could probably be done with one vfolder type and a balsa
If balsa is set for reference vfolders then balsa would act like the
first case. It would delete the Message from each of the vfolders then
from the source.
If balsa was set to copy on delete then it would be more like the
second case. First balsa would delete then Message from all of the
vfolders. Then it would retreive the message data from the source and
use addMessage to put it into one of the vfolders. Next it would get
the Message* from that vfolder and use copyMessage to put it into the
others. Finaly balsa would delete the source message. The vfolders
know to treat the message differently because Message->folder=NULL.
This means that balsa must use its own copy of the Folder*.
