In the single-user/desktop case, the application can spawn the server
sub-process if it's not already running, and the server sub-process can
exit when it has no connections.

Agreed. A true MVC with complete disconnection of business logic means
a less-usage UI. You want the UI to be able to inform the user as soon
as possible that there is an "error" in their input. On the other hand,
you want that error-checking to be done in a way that *ANY* UI can
leverage it (e.g. is my split transaction balanced?). There-in lies the
difficulty and challenges, because different UIs are going to want to do
that checking in different ways.
For example, on a webui you would want to have that checking done in
If everything is REST (or REST-like) then you MAY be able to perform
intermediary "validate" calls somewhere along the way to provide more
real-time feedback. You may not want to wait until the end to perform
