In fact I was thinking about caching type/creator/comment/icon/other
miscellaneous information with the data the catalogueing daemon proposed
by Adrian would collect.
Adrian, what do You think? This way all the necessary information an
enumerate I assume would need could be in one place, hopefully sparing a
lot of disk seek time - my biggest complaint about netatalk performance
was always the excessive seeking during enumerates, which eats away
precious disk bandwidth from more productive uses.

PS: Wesley, did You receive my second message regarding the website
creation for Adrian's version?
