If you sow the seed and jelly in a dampish compost, then the jelly will break down gradually and allow the seeds to germinate.
By bottom heat, I simply mean placing in a propagator which has a heated base. That is necessary for the likes of the UK but you may not need that. I can't see the advantage in soaking the seeds first.
I don't know about blogs but all I can say is that I used the above method 2 years ago and harvested a good few fruits 18 months later from 2 of the resulting vines. I kept them in my GH and the seeds were from fruit I purchased in the supermarket ( i.e P. edulis ).
When I purchased a packet of mixed passiflora seeds some years ago, none germinated and I took the advice of someone who suggested fresh seed works best.
Hope you have some success.
