[Xitami] FTP upload? Virtual-Host?

[xitami@lists.xitami.org]

Hello,

I have multiple Virtual-Host setup that I would like to create ftp for 
each (seperatly, something similar to a CVS system.) Allow for
authentication on upload but downloads can be anonymous without
password. My default.cfg has been changed because I had read
this would help secure the server. Each V-Host has its own .cfg 
aswell. Would someone please advise how this might be 
implemented...?

"Example files would be better than any explanation"

Also, has anyone written a server-side extension for Anti-Virus,
allowed IP's (configurable), etc. Ive been on the look out for 
extension (anything other than perl. or compiled code)
Is there a GSL Scripts repository somewhere? I would be happy to
host a repository if people would submit these to me.

Thanks in advance,
Euman
