How would one deal with systems of equations (i.e., reg3) and 
concurrently have heteroskedastic-robust standard errors?  Would 
bootstrapping with reg3 just be the simplest solution?


In the absence of cross-equation constraints, just estimate each equation with single-equation methods, i.e. -ivregress- or -ivreg2- using robust or cluster-robust VCE. Nothing is lost in doing so beyond a possible gain in efficiency.
