Rob points out that I don't really know about your security approach,  
so my above comments may not be entirely appropriate.  I guess what I  
was trying to say is that it wasn't clear to me from a security  
perspective that moving batch_create to the server would be helpful  
for you.  I'd be interested to hear about your security approach  
though, and will refrain from making comments about it until I have a  
better understanding of it.  :-)

In a different context, Phil and I have discussed the issue of the  
server knowing the source of a request.  It turns out this isn't an  
easy thing to do, at least for BMI tcp.  Phil has added some code to  
BMI tcp in a separate branch that provides the functionality  
internally in BMI, and it shouldn't be hard to export the info through  
a get_info call.  Let us know if that's something you're interested in!
