Hi Ben;
My suggestion is to have SAP handover the PB product to Appeon and let them run with it. How bad could that be?
When you consider what Sybase and SAP have done with PB over the past decade (basically SFA) versus what amazing things Appeon has done with PB over that same time frame AND also in particular over the past few years alone! They get my vote for best potential to move the product forward!
