This became a hot discussion issue in magic the gathering online (MTGO). I always felt my shuffles in MTGO felt different somehow than my offline paper shuffles. It's hard to know for sure when its all closed source. I know a lot of people were suspicious though.

Closed source doesn't need to stop you - even if a server was dealing out the cards you can still do a randomness test on them once you gather enough deals, but you would probably need millions of hands of data to do the analysis (see: dieharder tests)
