100% Rye Pizza Base Recipes? I'm looking for a 100% rye pizza base recipe. The recipes I can find all combine the rye with other flours (typically wheat based). I know it is possible to create 100% rye based pizza bases as I know of one pizza place in town that sells them. 

I understand that they had to do something special to keep the pizza base from falling apart. I don't mind experimenting a bit to find a recipe that works, but I could use some ideas on where to start - what sort of ingredients might bind the rye so that it doesn't crumble as a thin pizza base and maintains a low glycemic index for my diabetic wife.

The only dietary requirements would be that the various ingredients maintain a low glycemic index or a specific ingredient with a high glycemic index can be counteracted by some other ingredient. And only using rye flour.
Have you considered using 100% rye bread as your beginning and going from there, rather than pizza crust?  Peter Reinhart's Bread Baker's Apprentice has a 100% rye sourdough bread that might suit your needs, although it will be a time consuming process.  A preview is online in Google Books.  The recipe is similar to a Neopolitan pizza dough - just basic ingredients with no fat.  Because of this, I'd roll out the pizza very thin, New York style, for a crackling crisp crust.  If you don't want to buy the book, many local libraries carry it in the US, at least.
