Glad to see progress on this. We're currently debating whether to start with this spec, or develop a file transfer method that is in the OTR band rather than in the XMPP band like XEP-0047. Being in the OTR band seems like it would provide extra benefits of hiding more meta data, like the fact that a file is being transferred, the rough size of the file, etc. Having the file transfer happen in the OTR band could provide a fully hidden file transfer method by combining things like randomized padding and packet size quantization, as well as slaving transfer timing to actual messaging patterns or other such ways of hiding the file transfer timing. .hc _______________________________________________ OTR-dev mailing list OTR-dev@lists.cypherpunks.ca http://lists.cypherpunks.ca/mailman/listinfo/otr-dev
