The site has amazing Perl, CGI, SSI, etc. support. As far as "in-place editing", I just wanted a way to do a file listing other than FTP, like a cPanel file manager or such. When I asked on the member forums, I got a no, but it looks now like they have WebFTP and something called sitemanager that will do what I'm looking for. I'm still skeptical.

I'll look into wget as you and others have suggested. Thanks!
