Please add file "pass through" so you can share a file through someone elses computer, with a option to turn it on/off.
Search hits go through that someone elses computer and it responds as if it has that file, but then the file is transferred through. No way to know where the file is originating from, could be three or four computers it's passing through. No way to tell if a node is passing or not, or if pass through is on/off.
Make ultrapeers download and hold popular files for up to 24 hours locally for others to download, this will make popular files more available and faster to download.
Think about features that will prevent someone from DOSing your node to prevent your content from getting shared.
Some governments and "big companies" are trying to use DOS attacks and IP tracing to "censor" and control content on the network. This could also include governments that block freedom information to people who are being oppressed.
Thank you.
