I was suggesting that the presence of explicit support in the BPEL language for intra-process messaging would simplify deployment, since we would avoid having to perform deployment "tricks." >I would much rather find something simpler and more constrained, e.g., data flow through links (not thought through that yet, so please don't take it as an actual proposal). > Or perhaps an <invoke-self> activity?
