More people should use BiglyBT and its Swarm Merging feature. You get the ability to seed or download chunks from peers across separate torrent files.
It’s a shame because if more people used it, the BiglyBT devs might add hash-based merging (with v2 torrents) instead of just size-based. Hybrid/v2 merging is still possible, but file size is less reliable and caters to files only larger than 50MB.
Some kinda auto v1/v2/hybrid private<->public torrent maker plugin for BiglyBT would be… bigly.
Suppose one way around it would be to rent a cheap VPS in the UK and piggy back off the connection?
Otherwise, there’s a s2 ‘NORDiC’ version going around which is actually in English audio - just with various scandiwegian soft subs, so it’s defo out there. DM me if you still struggle to find it.
