[cowiki-dev] HTML & Embedded Images

I've been thinking about this and I was thinking that a few things
would be nice to have available in the cowiki package.  I'm not
putting these as feature requests because I figured they're somewhat
covered, and this is more of a discussion thing.  This is all based
off of previous conversations on the list.

1) an http accessible interface to the cowiki parser.  Whereas
currently, the template calls a plugin to retrieve a specific
document/node and parse it, what if there was a "seperate" php script
that given a node *name* could retrieve that node and display it
without the surrounding "theme" stuff.  Granted, it would have to read
session variables and what not to know if the current user has
legitimate access to said node.  This is more for future use when we
start doing things with js.  Basically, having some nodes of
user-editable documentation included in the database (taking great
care during upgrade situations to prevent overwriting any existing
nodes of similiar documentation) that some js/xml/rpc magic could
retrieve on the fly and display in a floating layer is "good stuff".

2) Either:
 a) A "seperate" file manager.  Using our existing access scheme,
allow people to upload media into the webserver via http post.  There
are already existing GPL web-based file managers out there, we could
choose the best and integrate it, or provide a modified version as an
optional add-on to cowiki.  The embed plugin could take an unresolved
link and take you to an somewhat pre-filled out upload form on the
file manager.

-or-
b) Add a files table to the database and use some of the common
methods for storing binary files in a mysql table.  While I don't know
how practical this is, especially with larger files, I know it's been
done many times before.  A practical upshoot to this approach is that
binary files could receive the same permissions set as the document
nodes.

-or- 
c) A combination of the two.. Use a home-brew web based file manager
to manage the uploading/renaming/deleting of files on the server in a
specific, restricted directory, but also maintain a database table
listing the files uploaded and use the same permission set as the
regular document nodes do.

3) A plugin that can retrieve an external html file.  Embed doesn't do
this, but it would be pretty simple to implement, and it would allow
people that need to put some fancy pages in place the ability to do
so, especially if implemented alongside #2 above.
