It's possible. Does not mean that typical enterprise is doing it.
OpenSwitch and SDNs in general are big data center toys.
But as long as we're talking routing traffic up to 1Gbps for that
typical SOHO - you don't need OpenSwtich at all, stock Linux kernel will
do it just fine. It's the hardware that gets tricky here - they do not
set up that many Ethernet ports on a typical server/consumer hardware as
one expects from a typical switch.

In general situation it won't be cost-effective. You just cannot beat
the cost of D-Link switch ($250 for that typical 1Gbps 24 ports) with
the cost of 1U server ($2000 and up). One could try to cut the costs
with consumer hardware or even SBCs, but where come the questions of
reliability, remote management, etc.
