Re: Regarding The cRio
What I'd do is create a bootable (livecd) image and put it on the USB stick. Your co-processor board would boot up the "livecd" image and start running. You would put a script to run your user code in /etc/rc.local (that script runs after everything is up.) You do have an issue that it takes some time to boot up completely. It "should" be less than the cRio, but your mileage may vary.
Your user code would be the program that runs to do your image processing / sensor processing / etc. The nice thing is that you could write that code in anything (C, Perl, Java, Awk, Cobol, etc.)
You could write on the Host PC and then ssh file transfer down to the coprocessor board. It then becomes the same "code, download, restart, test" cycle you do with the cRio.
Remember Google is your friend. Somebody, someplace at sometime has done something very, very close to what you want to do and has written it up. So don't be afraid to us Google to search it out.
