Maybe it's unused because the only things that can use it are zip, gzip etc 
which are hardcoded?

However I hope some thought can be given to filtering/chaining of kio slaves 
for KDE 4.

>What do you want to use it for?

yenc based decoding of nntp streams. e.g:

amarok "nntp://my.news.server/a.newsgroup/an_mp3_file#yencode:/decompress"

It's a bit more complex than that (e.g multiparts) but you get the idea. The 
point is that amarok or whatever else shouldn't be aware of what is 
happening.

It already is KFilterBase derived. kurl.hasSubUrl() will stop it running if 
its KFilterBase derived or a plain old kio slave.

Is there anyplace where I can read up on what is being discussed with regards 
to KIO and version 4? I haven't noticed anything on these lists.

Cheers, Paul.
