The physical cabling should look like this:
<MIDI controller>[MIDI Out] -> [MIDI In]<computer #1>
<computer #1>[MIDI Out] -> [MIDI In]<computer #2>

<..> is a MIDI device
[..] is a physical MIDI port
-> is a cable

MIDI Events from <MIDI controller> will then get to <computer #1>. However, that's where they'll stop, unless you do something to forward them on. On <computer #1>, you can run MIDI-OX like this:

{MIDI In}=>(MIDI-OX)=>{MIDI Out}

{..} is an Windows MME MIDI port.
(..) is a program running on a computer.
=> means the port is open by the program.

MIDI-OX will send MIDI Events it read from the {MIDI In} port to the {MIDI Out} port it's connected to (and they'll be connected by default).

However, most Windows MME MIDI drivers only allow one program to open a MIDI port, so this would stop you running any other software on <computer #1>. The way around this is to use MIDI Yoke as well as MIDI-OX. MIDI Yoke is a Windows MME MIDI driver that acts like a MIDI Out port connected directly to a MIDI In port. The advantage is that the ports can be shared. So you set up like this:

{MIDI In}=>(MIDI-OX)=>{MIDI Yoke Out #1}
{MIDI Yoke In #1}=>(MIDI-OX)=>{MIDI Out}

Note: that's only one instance of MIDI-OX running.

Any program on <computer #1> can now use {MIDI Yoke In #1} instead of {MIDI In} to read MIDI Events from the <MIDI controller>. And a program can write MIDI Events to {MIDI Yoke Out #1} and they'll be sent to <computer #1>.

Why Don't use a LAN/Ethernet Cable ????
if U Use 2 Laptop you can Adhoc 2 laptop with out cable...

if u use PC :
Google "Ethernet MIDI" It's Free and can run mutiple Instance
but "Clean/Simple/Good Performance" try it

Makes no real difference but I'd say MIDI over Ethernet is just one more thing to go wrong, myself (but I've never used it).
