Right. I don't really have time to study the particulars of your proposal but
maybe you can consider to just 'trust us' when we say that
-- you really do want a package
-- others have done packages for user-facing MCMC / Gibbs (cf Whit's rcppbugs)
-- you can still allow the user to putz around ad-hoc with sourceCpp.
