* transferring files from one 'real' operating system to another without loosing file permissions, attributes & other meta data.
* if you have to transport 'commercial in confidence' files either into or out of the US of A (given the crazy warrantless search rules recently upheld at US airports, and assuming that you intend to meet your legal obligation to protect the data) can you think of another place where an encrypted binary blob would be more likely to fit in with the crowd?

RE: TWIMC = To Whom It May Concern...
RE = with regard to / further to
FYI: US of A = United States of America... (in case you were wondering)...
FYI = For Your Information. (i.e. you aren't expected to 'action' anything)
i.e. = id est = that is = that is to say / in other words

Neither of those are uses for a DAP.

Surely there would be no need to implement any of that in Rockbox - you simply use the DAP as an external hard drive on an operating system which supports loopback file systems.
In fact, in the example you give of wanting to transport sensitive information, having the DAP able to natively read the loopback file system would take away the protection that the otherwise hidden files had.

In addition to listing partitioning the device as a work around on the NoDo list, perhaps consider mentioning loopback filesystems.

Since you clearly understand my initial post, What do you think about adding it as a suggested work around on your NoDo list?
Please advise
Thanks & regards

p.s. in case this is STILL not clear to anyone, I'm proposing a change to the website.
p.p.s. I am not proposing a change to Rockbox.
p.p.p.s. I've already done this on my X5. I've provided a link to a suitable manual. (Llorean please note my restraint here :-)
JdGordon:
I cant see what this has got to do with rockbox.. but anyway, the NoDo is on a wiki, if you want to add it, please do.
BUT, its not a work around for the other filesystems nodo point. the point there is rockbox wont be made to support reading from other filesystems (the big one if HFS+ for mac formatted ipods, or ext2/3 for linux boxes). we dont care about your data secutiry, do what you want with other files on the DAP...
and anyway, storing a loopback FS on a fat32 formatted disk is pretty silly... max 4gb storage, and anyone smart enough will know how to read it anyway
