It all falls on the application really. There's nothing wrong as such
with opening ports on your firewall, but what the machine on the inside
does with the data is another issue.

For instance, if you're running a peer to peer application, you have
toplace some trust in it that it's not going to give the entire contents
of your hard disk to the entire world.

Opening ports on your firewall to allow traffic to Windows machines
could compromise your protection from spyware doing nasty stuff, or
allow backdoors or trojans to function.

As for the software in question, I'd just skim sites like the one you
mentioned to see what the ill-effects may be.
