Do I really need a catch can??

True. A catch can plumbed between the crankcase vent and driver side turbo will not completely stop the condensation issue. On some trucks, however, it will help. The liquid that was in the driver side catch can is exactly what is building up in the CAC on my truck. The liquid is thin like water, smells of gas, looks like snot, and has a very small amount of oil in it. If one were to drive in such a way that produced more of this mixture vs. other drivers, I could see how this could give the same symptoms as the condensation issue without being in an environment that is capable of actually producing condensation. I also partly blame this mixture ( and sub-zero temps) as the reason the OEM CAC cracked and split at the bottom in Dec. 2012. If your truck does not produce this mixture then maybe catch cans would be an unnecessary purchase.
This week I'm hoping to have time to remove and clean out the CAC and all intake piping. I'm also going to drill a weep hole in the CAC. This will tell me how well ( or not) the catch can is working and hopefully I will never get to experience the condensation issue.

If you took about 10 minutes to study the plumbing on the EcoBoost, it should become more clear? I gave sources previously that you will find give a very good explanation if you care to take the time to check it out?

I just don't believe the catch can accumulation is related to the cac condensation problems. Blowby valve buildup via the pcv system is a chronic condition and can be prevented by the catch can . Cac condensation is an acute problem caused by water condensing in the cac suddenly being sucked in. Nothing about this catch can will prevent the acute problem.
That doesn't make it a bad idea to protect the intake from blow by. But I have seen no compelling evidence that it can treat the condensation problems and suspect it is slick marketing to increase sales from fear.
I might be convinced that the oil in the cac is acting as a nucleating agent that promotes condensation accumulation . But nobody has made that argument and I'm unsure if it could be true.

Would it be possible to run both sides to a single catch can via t-fittings?
Or would it not be possible due to the passenger side being pcv all the time and the driver's side only acting as a pcv under boost conditions?

It might be possible using check valves. IMHO, it's best to keep those lines separate. I'm not saying it's the only way, just the way I prefer to use the cans.

Boost :)
I have run one in my Supra in the past and it has two ports on the top for the valve covers, baffling inside, and then one port on the bottom as the source for vaccuum from the intake track.

I wouldnt run a pcv style at all personally. Id naturally vent the crank case to a catch can and just close off the intake side of it all together. Works on all the race cars iv been around and built, and yes majority of them are turbo cars . Just my $0.02

I've looked through the sources. I don't see much supporting the claim. And I've looked at the plumbing pretty well.

Moisture does not automatically appear, it is always present, my point is to capture it before it can condense!

IDK what sources you are looking at, so I will try to provide some links.

I don't think you're talking about he CAC condensation that results in shudder/poop-my-pants problems that everyone is discussing these days.
