PASV is almost universally supported by FTP servers. My understanding is
that this is both because PASV is a required part of the FTP protocol spec
for the servers, and because Mosaic-like programs with built-in FTP clients
tend to use PASV mode. With the rapid growth in popularity of such programs,
it seems likely that almost all FTP servers already support PASV mode, and
that those that don't will either be upgraded or replaced very shortly.
Now, as far as finding clients that'll use PASV mode... Well, like I said,
the Mosaic-like programs with built-in FTP support generally use PASV mode,
so that's a start. I'm sure there are some standalone Mac/PC FTP clients
as well that use PASV mode, but I'm not sure how widespread they are.
