[Rd] Struggling with S3/S4 interface issues and External Pointers

I'm currently working on embedding R into the Apache2 webserver (with
some positive results...), but I'm struggling to identify the best way
to expose the apache data and functions to R.
A couple of thoughts:
In light of the recent discussion on "S3/S4 classes performance
comparson", I'm leaning toward implementing the interface with S3 style
classes. I appreciate anyones advice on this.
I JUST found (after roughly 6 months of studying R) Luke Tierney's note
on "Finalization and Weak References in R". From the developers page,
this note is listed as a "preliminary mechanism", but I scoured CRAN and
noticed packages like RODBC and XML are using it. Has this mechanism
changed from "preliminary" to "production" yet? For storing pointers in
R variables, I've been using integer vectors which is what RMySQL does
but doesn't seem natural.
