SOM in scipy.cluster

Greetings,

I'm considering using self-organizing maps for mining some lightning  
data, and info.py in scipy.cluster mentions that implementation of  
self-organizing maps is under development. I've found a few examples  
written in python around the web, but none that are likely to be  
efficient enough for my use.

Is there still interest in including SOM in scipy? I'd be happy to  
coordinate on a contribution if nothing else is under way.

Thanks,
Eric
