I got myself a wireless remote for my Canon Eos 50d recently. Works from up to 100 yards away. It was only 18 quid on amazon and works really well.
I have fart-arsed about with it tonight to try for light trail with 2nd curtain flash. Got the idea right but execution needs more work on it. But you'll get my drift regarding effects you may get.
