Polyvinyl Alcohol for Support Material

Has anyone tried polyvinyl alcohol as a support material? I know the melting point is pretty low, but its water soluable..

Just wondering,

Adam

it was sold by makerbot but i think they dropped it not enough demand, but with more dual extruders coming onto the market i think that may change again.

Has anyone tested how well PVA sticks to ABS and/or PLA and also how well ABS and/or PLA sticks to PVA?

Did all the PVA end up disolving in the end gr0k?

Printing with support interestes me a lot, I wouldn't be above making my own PVA filiment if it was going to work well.
