Envirolet composting toilet on a narrowboat get blogged

Envirolet, the big name in composting toilets, has a blog called Envirolet Buzz, and it's a great way for them to garner attention for their product.  I work in PR and I think it's the right thing for them to do. Today they turned their gaze to English canal narrowboats.

They are lacking a good case study of a composting toilet on a narrowboat, and so they resorted to the Wikipedia entry on 'what is a narrowboat' to illustrate their point, although the boat in the picture doesn't have a composting toilet.

Granny Buttons doesn't have a composting toilet either, although by the promises they make, I wish it did have.  (I'd rather have the smell of drying poo in the cabin than the smell of diesel)

So I've included a picture of Granny at Banbury instead. 

Is there a composting toilet on a narrowboat?   I'm still waiting for a reply from the UK distributor so I can report on its promises.  Richard, where are you?   Anyone else want to distribute Envirolet toilets to canal boats in the UK?

Update:  Ah, there you are!  canalshoponline, I owe you an apology: that last para suggested you hadn't replied.  In your defence, I'd sent you a long drivelling email last December; if you fell asleep before you reached my request to meet anyone who'd installed a composting toilet, then I don't blame you one jot.
