Well, the Rcompression package on the Omegahat package does have some facilities for it.
It doesn't do it in memory, but does handle issues of moving disparate files to
a common temporary directory and getting things in order generally to create the zip
file. But it currently uses the external zip executable to create the archive.

I probably will get around to implementing a version in memory as it has been
an issue that has nagged me for a while. And we have the code for it.
