 Some VPNs allow to setup portforwarding. Tor exit nodes could provide a
 similar feature. the client tells an exit node that it should forward port
 x to a hidden service which could be a conventional hidden service or a
 temporary one for a normal client. the exit node then asks the hidden
 service if that is realy him who asked. then the client could set up a
 dynamic dns and update it everytime he switches the exit node. (binding it
 to the circuit might be possible too but is too unstable)
 the advantages are:
 * hidden services can be accessed from the internet without a tor2web
 service.
 * not only webhosting is accessible from the outside internet
 * average users could have anonymous inbound connections
 disadvantages:
 * how to do port usage limiting if the exit node doesnt know an ip?
