This will happen normally via routing. For example if the address is
192.168.1.10/24 and the system wants to talk to 192.168.3.50/24 the
system will need to go through a router, even if the device is part of
the same logical segment.

Exactly right. VLAN's are a layer 2 thing so your options for creating a
VLAN are:
group VLANs by switch port
group VLANs by MAC address
Since we are talking a single NIC with multiple _layer 3_ addresses, you
have no way of breaking out communications into multiple VLANs.

Hummm. Depends on the vendor. This could be interpreted as a backbone
(meaning 1-23 need a router to get there) or a global VLAN which
includes all ports.

Sounds like what you really want is an ASIC router (or layer 3 switch
depending who you talk to ;)
Just out of curiosity, why do this? Besides adding a high level of
complexity, it does not really buy you anything unless the systems
connected to 1-23 are generating tons of broadcasts.
