Cool :)

Yes it would, but it would also be a lot of work.  Recall that Conrad put a
few man years into Armadillo, and Rcpp et al weren't build overnight either.

Mark, and others, have put some thought into this but it is ongoing...

Lots of interest in ZeroMQ. Whit (CC'ed) just submitted something for our
upcoming fourth R/Finance conference about ZeroMQ and AWS.  Bryan Lewis (also
CC'ed) also has some code for R and ZeroMQ.

| Hi all,
| 
|  
| 
|  
| 
| I'm trying to gauge how hard this would be before I spend too much time down

| approach.
| 
|  
| 
| Any advice greatly appreciated.
