I don't know what interactive R might be, and how that might differ from 
command line. As far as I know, there is only one 'type' of R (pretty 
much command line, unless you are using some tcl/tk widgets), and 
biomaRt works for that.

Again, not sure what you are getting at here. There are many things in 
the annotation world that don't have a neat one-to-one mapping. Anyway, 
have you looked at the vignette in biomaRt that shows how to make an 
annotated HTML table using biomaRt and annotate? This cleanly handles 
any one-to-many annotations, and the result isn't completely horrible to 
look at...

HTH,
