RE: Building EOS dApps

i have some doubts

Lets say I want create an app like facebook over EOS but with next characteristics.I want this app to deployed in two countries and be compliant with the laws of the two. I could deploy 2(it will be more) blockchain based in EOS with its constitution for each country and these two blockchains could comunicate with each other(i have a person in one blockchain that is a friend or is following a person from the other blockchain). I know this could be done through inter blockchain communication. My question is: is this feasible, would I get good time responses for this scenarios close to real time apps ?. I saw in an article from a block.one member that you had this for instance
{
receiver:inite,
scope:eosio,
name:transfer,
data:{
"from":"inite",
"to":"inita",
"amount":10000,
"memo":"memo"
},
data_access:[
{"type":"write","scope":"inite","sequence":1},
{"type":"write","scope":"inita","sequence":0}
],
region:0,
cycle:0
}
what is the field region for? is it refering to phisical places, America, USA?
If that the case i could then model my use case with 1 blockchain and diferent regions each one with different constitution(or the same but differentiate each region in the constitution).
Could I??

or I could deploy a blockchain with differents dapps(one dapp for country where i set a bussiness) being the dapps compliant with the law of the country which is destined to.
