I have a LAN that I want to split in half, but leave all the IPs the
same (they'll still be on the same subnet).  I then wan't to
transparently bridge these two (now) separate LANs back together. =20

I know that I can do this by having one computer with two NICs in it,
one on each segment.  But what I want to know is if I can connect one
computer from each segment together using a serial cable, and both of
them would be talking PPP (using tun devices) over the serial port. =20

Can I do this and transparently bridge across the serial cable?

The above scenario is just hypothetical to be able to ask the
question.  The actual implementation would be for a very large, sparse
SCADA network with many separate branches leading to separate LANs
separated by long distances.  And the serial connections would be
RS485 rather than RS232.

TIA for any info/pointers offered.
