i'm trying plain text this time. hopefully cleaner. should really find a better
free e-mail account.

is this true even if the CVS server does not answer? (i.e. port closed on firewall)

Sorry to say, when you use pserver, by accident or otherwise, your password
will be exposed (albeit in a trivially encoded manner).

You could avoid this by, either:
1. Not installing the pserver protocol on your client machine. (If the
protocol isn't there you can't accidentally use it... but you then won't be
able to use pserver to connect to any anonymous sites).
2. Connect indirectly via a proxy which munges from pserver to sserver... I
just posted a message to this list about my cvssproxy add which does just
that :-)
