seen that on raidenftpd's page.
don't know if this is off any interest , talking about performances.
maybe it can make listing faster or transferring not compressed files.
sounds good to me since lots of clients start supporting it. in addition there is an rfc describing it.
maybe this can be used on a file-extension basis to save cpu time (compressing all the data could be a waste of time). meaning it would on-the-fly compress a .log file and wouldn't compress a rar/zip file.

Please do not hesitate to comment on that technology.
