It's important to recognize one very significant difference between
RELOAD and Skype:
Skype controls the software you run and so can make you act as a
supernode--or at
least make it fairly difficult to opt out. By contrast, RELOAD will
presumably be open
software (at least the protocols will be open) so you cannot force
users to run relays.
