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.
My mentor pretty much told me that a second PC will not be needed, since the crio is pretty powerful as it is, but I am still keeping the PC idea in mind, the problem is that the usb idea is "fragile". the USB can pop out mid competition, so thats dead. I was thinking of just using a SS drive (no moving parts) instead of HDD, so it can't get messed up as bad
