gelatin for e/o

Question

hi. i read through your previous responses to this issue and i am just a tad confused ..well firstly this is a brand new idea and its always hard to get acclimated to change but basically i was wondering if this "psak" is just applicable to sefardim and if not (meaning if it applies to all) then would it be possible for you to site ashkenaz poskim who concur w/ this ruling and where i can find sources for this? thank you
