firewalls?

The limitation of this method is that you do need your own port exposed to the internet. The advantage of this method is that you don't have to trust a third party.

For the explicit example above, your guest's firewall would have to be pretty brutal to not allow port 80 through.

Yeah it was mostly the senders firewall (or the NAT you find on most consumer routers) that i had in mind.

The OS may also balk at opening such a low port as a user, now that i think about it.
