Sticking with the concept that R needs to be installed in order for RInside to work: one could imagine how the exe could package in the bits of the R project it needs, and unzip them to under /tmp/ when it starts up, and remove them afterwards. Or even into a ramdisk. But, if security of the delivery binary is the issue, how about taking that one step further. Install R into a directory structure that was created with encfs [1]. The user will need to input a password each time they start the app to mount the unzipped encrypted directory. (That adds an overhead to reading the files, but not to running them (?)) Darren P.S. To be honest, I originally thought encfs kept everything in a single file, which would have made distribution trivial. But it copies the directory structure, meaning there is one encrypted disk file for each real file. I'm sure I've seen/used something where there was a complete file system in a single file...
