Jothar –

2) Sediment of non-kosher wine which has been processed to the extent that it can no longer produce a good wine flavor, yet now it has a new flavor; since the chemical process is such that the sediment cannot be made into the new thing without losing the flavor of issur, it will always retain its status of pagum, even though through the chemical process it now has a good flavor. This is the argument of ???? ?????.

To answer your specific questions:

He is not mechaleik between different types of bones. The ikkar is that they have to be dried out, but even if they aren’t naturally like that there’s no difference.

He does not indicate a length of time for processing. Point #2 would indicate that there is no amount of time, it is rather the metzius of the processed product – is it possible for it to come into existence without a p’gam of the original flavor – if not then the panim chadashos product is always regarded as ta’am pagum of issur. From my limited understanding of point #3 it only applies where the product is still not fit for consumption.

Regarding pigskin, I would say he would be matir because of #2 and maybe #3 as well. I am not sure about #1. But he is not making a tziruf, he seems to be saying various independent heteirim. Therefore I would say that even if you just had #2 he would be matir.
