I set something up like this for myself at (minus the file
limits) its basically just a simple zodb based remote file storage for
friends. basically to do it you can't let your visitors have access to
your manage screens.

example implementation.

create a folder called filesystem 
stick all your adding and managing methods in filesystem
add a size limit property to filesystem
for each user create a folder under filesystem.
that folder should probably have a property called current_size

basically you're going to have forms for people uploading a file. on the
page where you would do the manage_addFile stuff you're going to
implement the logic. check size of the file with _.len(file) on the form
submit page and add to current_size see if its above the limit. if it is
don't add tell the user why. if it isn't add it update the current_size
on the directory. voila.

here's some sample code which does the basics of getting file info 
without the management logic to get you started. it pretty prints a
table of file info.

<table align="center" border="1">

<tr><th colspan="4"><dtml-var id> Directory Contents</th></tr>
<tr><td>File Name</td><td>Type</td><td>Size</td><td>TimeStamp</td></tr>

<dtml-in "objectItems(['File', 'Image'])">
<dtml-with sequence-item>
<dtml-call "REQUEST.set('DirectorySize', DirectorySize+size)">

<td><a href="<dtml-var sequence-key>"><dtml-var sequence-key></a></td>
<td><dtml-var content_type></td>
<td><dtml-var size></td>
<td><dtml-var bobobase_modification_time></td>

<dtml-call "REQUEST.set('DirectorySize', DirectorySize/1000)">
<tr><td colspan="4">Total Directory Size: <dtml-var
