I think the whole point here sheds light on a very important aspect of bitcoin going mainstream, which is an average mainstream user not to be blocked by an entity in order to access the blockchain..
Definetly there has to be a project where people can connect to blockchain irrespective of the isp provider

Could it happen like that?
To block bitcoin node traffic the ISPs would need to filter out all traffic doing something called deep packet inspection for all international traffic. As far as I know only China, with its Great Firewall, and some others dictature-led countries are capable of doing it. I am quite sure India doesn't have this capability. They, most likely, can only blacklist individual IP addresses and domain names.
you could use TOR in case of that, i think.
An ISP can block a port very easily, such as 8333 or 8332
If an ISP blocks your port you can just use port forwarding and get around it.
Hey bud, look up the definition of port forwarding before you spout random BS, eh?
Technically, even if there was a "great firewall" on the border of the country, all it'd take is a single node to smuggle data [VPN anyone?] between that firewall. They'd need to implement a firewall / filtering policy at almost access layer to prevent this sort of thing going on.
Honestly, from a tech stand-point, it's nearly impossible to block a competent user from getting around a filtering system other than literally creating a country wide intranet not tied to the internet.
I wonder if it is possible to address this by building a port hopping wallet. Correct me if I am wrong but isn't that how music and video downloaders got around the riaa?

Nobody can shutdown bitcoin network, the problem however is mainstream people shutdown by their government by askng the isp who are financed by the banks
The only issue I can think of is finding nodes on non-standard ports. Are any of the seed nodes on ports other than 8333?

Well there is nothing saying you have to use port 8333. You can easily swap to another port.
yeah, like say, port 80.
Wonder if 53 will work?

It can be done, though it does need quite large investment because doing it at high-speed isn't easy.
Adding additional layer of encryption could fix some of the problems. Forming a connection could still be an issue. Basicly lot of things can be blocked on Internet, but these blocks can be circumvented by encryption, VPN and so on...

Are you really serious!
After all the promise of decentralized revolution and financial renaissance, all can be just stopped by just blocking a 4 digit port.
I am going to cry!
Well to make it easier, couldn't the intercontental cable providers block this? As in the people who actually own the fiber under the sea. It's only like 4 companies.
Who are those 4
Here are the internet service providers for normal internet service providers:
UUNET
Level 3
Verizon
AT&T
Qwest
Sprint
IBM
Most of them are US owned companies but there is probably more.
I think i should really buy some namecoins and support it

Since yesterday 300 websites are blocked in India by all internet service providers including youtube, even piratebay is blocked.
So depressing and sad , I am pro net neutrality and the reason the blocking is happening is because the media barons want to make money off FIFA telecast..
Now i am really concerned and scared what if the bitcoin network is blocked by all the ISP of a country?
Could it happen like that?
