We can't connect to cosmos-hub now, right?

I am learning cosmos-sdk now. And it turns out that there is no tutorial about how to connect your chain to cosmos-hub. So the cross-chain future is still not available? BTW, I really have a hard time reading the source code of IBC module. Looks like we need to implement a lot of codes if we want to have cross-chain feature just like what the basecoin project? Thanks.

The IBC protocol is in the final stages of specification here

Here is an example of an application built using the prototype IBC code the cosmos SDK team has been developing.

Looks like the example project is not really using the codes in cosmos-sdk/x/ibc module, and it really changes a lot of codes…
