[R] R as a web service

[Carlos J. Gil Bellosta]

Dear R-helpers,

I have been inquired about the possibility of developing a web
distributed scoring system: a model is created in a central location,
users fill a form in their browsers, and the central server calls this
model and returns a YES/NO answer to them.

I am tempted into using R for this assignment. I have used Rapache for
similar tasks, but I am afraid that it is too of a novelty for many
backward looking IT departments. For a number of reasons, a Java based
infrastructure (tomcat, web services, etc.) would be much more palatable
for them.

My wishlist is as follows:

* Minimal infrastructure changes in case of (statistical) model updates
or changes.
* Solid management of concurrence, so that simultaneous connections do
not interfere with each other.
* Maximum efficiency so that new connections do not require a fresh R
startup.

Any ideas on how to achieve this? Any documentation available?

Best regards,
