Sure, any way of getting the J tarball onto the RPi's SD card is ok. I just opted for direct copying because my internet connection was flaky (it's fine now).
The "conventional" way of downloading a new app is to use "apt-get" in a console session, which accesses the Pi Foundation's server. This does require your product to be sniffed-over by the Foundation. J's tarball sidesteps all that. I see however that www.dyalog.com are delivering Dyalog APL for the RPi by hacking into "apt", a method that might be adapted to J. The only advantage I can see (apart from doing things the done way) is to allow apt-get to uninstall the app as well as install it.
