I've started to look at it because I've written some Spotfire extensions that use R for computation and some people have expressed interest in a server version.
General criteria are:
- Linux and Windows
- Extensible by modifying text files
- Accessible and understandable by a typical R user
- Self-contained and easy to install
Since Rapache doesn't have a Windows version, it needs to be run within a VM. I really like the idea of using standard Apache server configuration procedures along with either standard R scripts or "brew" templates. But I lost patience with working in a Linux terminal within a VMPlayer window.
