There was an idea to have a daughterboard or “shield” which would give access to all available pins and ports on JeeNode (like Port 1 to 4, I2C and SP/ISP). The desired size of daughterboard was the same as JeeNode, so it could fit well on top of the main board.
Having that in mind I came to a solution of using the already available JeePlugs.
So I flipped two JeePlugs by 90 degrees and surprisingly for myself I found out that they cover I2C and SP/ISP interfaces as well - see the pictures here:

Well, in order to cover the I2C port the JeePlug has to be shifted by one hole to the left (towards I2C port). That leaves one IRQ and one PWR pin in the air, but they are doubled anyway on the same JeePlug, so all is covered and nothing is missing.

NOTE: To make this working some traces have to be cut on the JeePlugs, but they are all very thin and easy manageable.

What I like about this solution is that the JeePlugs become as wide as the main board and so it fits better in my project box.

I must say many thanks to Jean-Claude for designing this beautiful JeePlug, which can be used so many different ways ;-)
