Rough idea:

COPY(my_address, my_priv_key, copied_address)

From this moment onward, every operation done by copied_address is copied by my address, in proportion to our funds. Meaning if copied_address holds X MSC and my_address holds Y MSC, and copied_address now places a market offer to sell Z MSC, then my_address will sell Z*Y/X MSC.

This of course needs more details to account for multiple currencies and assets stored on the same address.

Just thought I would post a little explanation about this feature.

Example:

Alice has 1000 MSC.
Bob has 100 MSC. Bob thinks Alice is a smart trader, and tells the decentralized Mastercoin system to just copy Alice.

Now, Alice sells 100 MSC using a market order. Immediately after this, Bob will automatically sell 10 MSC (10% of Alice's action). Let's assume for 1 BTC = 10 MSC

So now: Alice has 900 MSC and 10 BTC
Bob has 90 MSC and 1 BTC

Note that Bob was in vacation in Thailand and wasn't near his computer.

Now, let's say 1 BTC is worth 20 MSC, and Alice thinks it's a great buying opportunity. She spends 2 BTC to buy 40 MSC. Bob automatically copies this purchase.

Alice has now 940 MSC, and 8 BTC
Bob has 94 MSC and 0.8 BTC

Of course, in real life there is slippage. Bob will always get a slightly worse deal than Alice.
