that's what i was thinking - the sleeve adapts it up to sd-card side. :)

this is what the n800 does - and my motorola rokr e6. although i really think
its a nasty hacky thing. i'd rather try the samba/nfs route (offer both samba
and nfs and windows users get their file sharing - and unix/mac guys get
theirs! :) let the community tune/fix samba - we just get ti to raw "kind of
works" state)
