Selecting unixfile plugin

Hi,
  After much digging around as to how to use the reiser4 compression
plugin I have found this message.
http://marc.theaimsgroup.com/?l=reiserfs&m=113190018626958&w=2

I'm using 2.6.15 + resier4 + metas patches.

I'm trying to set the default plugin to cryptcompress for a directory in
a r4 filesystem.

It seems that the plugins/regular is thought to be a directory when I 
echo "cryptcompress\0" >|plugins/regular

Trying various combinations of things inside regular/ like echoing into
label etc don't seem to have an effect when read back again.

It seems from the below link and grepping the 2.6.15 reiser4 patch that
echoing "cryptcompress" >| mydir/..../plugins/regular/label
should make new files in mydir use the cryptcompress plugin by defualt.

The info like http://www.namesys.com/cryptcompress_design.html seems to
be targetted toward developers rather than users. Are there any
references or logs of command line interactions to enable and tweak
compression/crypto aimed at end user consumption?

Also from what I've seem a 
sed s/metas/..../g 
might be in order for

Yes, it is. Although this stuff should be qualified as experimental.
If you have spare disk space and another box with serial connection,
then we will send you the setup..

Cool. I'm looking forward to playing around with it. Hopefully I can
tailor the instructions to work with Xen or a filesystem mounted on
loopback (what I have at current) so the "spare machine" is somewhat
protected from the worst case.

I could generate the setup of scratch machine and serial connection if
this is required though.
