Pittsburgh IX?

[ML]

I was looking for information on any IX in Pittsburgh. Found PitX [1] 
..info is rather limited to say the least.  Is there any information out 
there about participants, size, etc?

Are there any other IXes in or near Pittsburgh by chance? I see 3Rox out 
there but seems to be a R&E network mostly.
