As a D licensed (master) parachutist with over 1,200 skydives -- and heli pilot (R-22) to boot -- I can attest that 'jumping a heli' is not trivial.
Even the venerable Bell-412 (Viva Rod Tinney!) HAD to be jumped 'carefully'. What do I mean by that? -- We HAD to 'exit' out *symetrically* so that the Lateral CG (along the Logitudinal (left right) axis) would remain within controllable limits for the pilot. Read: minimal left-right wobbling as jumpers exited.
With the extreme 'sensitivity' to CG (just think of how much you push the cyclic forward during solo flight pick-ups!) not to mention the LOW tolerance to 'down loads' on the skids -- I would NOT let anyone jump from an R-22 with me at the controls.
The R-44 is another story however...
