It depends on how big the ISP is, how determined it is, what sort of hardware
is available, etc. It is true that there may be some recognisable patterns in
our current traffic: there aren't fixed signature bytes as in 0.5 and as in
most protocols, but there may be other possibilities for fingerprinting at that
level. Eventually we will support steganographic transports ("make it look like
HTTP/VoIP/whatever"), at which point it is rather more difficult, but traffic
flow analysis will probably still allow identifying nodes with reasonable
accuracy - assuming you have the hardware for it - just like any peer to peer
network can be identified. Of course, the ultimate sanction would be to simply
block all communications between IPs listed by the RBLs as domestic! Long term
I would like to see non-internet transports e.g. wifi, sneakernet, etc, which
might enable Freenet to survive even in a very hostile network environment.
However, so far most countries with national firewalls have not been very
sophisticated...
