I was thinking of just the information that is provided when you  
type ?cmd in R. Not sure if other bundles have something like this,  
maybe the obj-c one does.

Well, you do need to somehow keep it running in the background and  
interact with it. I haven't been able to do that in a nice way. I  
think R CMD BATCH might be more closely to what i am talking about in  
question 1. Problem is, I found no way to tell it to output the  
information to standard output instead of another file, unless I've  
missed something.
See, what I want is to have R execute each command and return me the  
output so that I can start showing it, instead of running the entire  
program and then showing all the output.
Exactly what happens with tmruby.

Not sure really, just threw it there as an idea. I am not far into it  
to packages yet, so I was really thinking of the standard commands.  
But I guess this is in part provided by the syntax highlighting.

I just don't want to even have R.app running, ideally. Most work  
should be doable from within TM, that's what (3) above is intended  
for. But it just seems to me that R does not provide, at least it is  
not clear to me if it does, enough functionality to support programs  
hooking on to it and becoming its front-ends. But I must say I  
haven't spent much time with it yet.
