-pre and -post script are executed with the credentials specified in a 
WPKG Client configuration.
So when disconnected, and the credentials can not be verified (because 
domain admin credentials are used, and the domain server is 
unreachable...), it won't work.

And hence the "laptop mode" (or, "offline mode").

Also, I think it's pretty hard to write a script which would check if 
there is a reply from a server received below X seconds - with somehow 
limited built-in Windows capabilities - yeah, wpkg.js is another story ;)

In theory, it's possible right now - just write your -pre script or 
program like that (yeah, killing WPKG service may be needed, so it's not 
that pretty). Perhaps if it's a very demanded feature, someday...

They *can* be server side (and indeed, it is best to keep them on a server).
But how can you possibly execute a -pre script if you're disconnected? :)
