<p>It appears that bitcoin addresses using p2sh keys have a different prefix to that of normal bitcoin addresses. Do other altcoins such as litecoin, peercoin, dogecoin etc include this functionality?</p>

Most likely, they are 1:1 clones most of the time of BTC.

Upon looking at the source of a number of altcoins I have found that p2sh keys are built into all the ones I checked.

For P2SH, the first address byte will be:

> bitcoin: '05'  
> litecoin: '05'  
> peercoin: '75'  
> dogecoin: '16'  
> beavercoin: '05'  
> freicoin: '05'  
> protoshares: '05'  
> megacoin: '05'  
> primecoin: '53'  
> auroracoin: '05'

The tricky bit about this is that you can't nessesarily tell what network a P2SH address belongs to like you can with normal addresses.

The reason I wanted to know is so I could collate the version numbers for my project:
