This is an interesting idea. However, since I release minor updates to AFNI fairly frequently, at some point the user will be forced to upgrade at least the AFNI binaries.
As it is, I occasionally get e-mails from people complaining about problems that were fixed months ago. This is why AFNI now does a "version check" when it starts, checking in with the server here to see if the binaries are up-to-date. The next step will be an option to download updated precompiled binaries. (Don't ask when that will be developed - it's just an idea now.)
