As to the other, we would not have a business interest in simple communication across the galaxy at this time, but in getting ourselves back and forth. That is the goal. Make it happen.
Okay, just manipulate and measure the velocity then. It seems simple enough, in theory if not necessarily in practice.

I'd love to, to be honest, but I don't see it happening in my lifetime. Developing ansible communication, on the other hand and as has already been pointed out, has any number of applications beyond communicating with one's interstellar starships and colonies: The ultimate in uninterceptible communications, real-time control of our interplanetary missions, etc.
I'm just still unclear on why FTL communications would cause such paradoxes that they must be impossible, as some here claim.
I think we would have a lot of interest. Granted travel would be better. But instantaneous communication and control of remote probes.
We could build and send probes to nearby stars looking for inhabitable planets.
The 26 nearest stars range from 4 to 11 light years away. If we could send probes that could reach 25% of the speed of light, we could have probes to 26 planets in times ranging from 16-44 years, but once there we wouldn't have to wait 4 to 11 years for results, we would have them instantly.
Just compare how much trouble we have with mars probes because of the time delay in receiving data and issuing commands.
Plus as someone pointed out earlier. Instantaneous, unbreakable, unjamable military communications. That's big.
