The good ole owner's manual states that you should not exceed 5 MPH with the rear diff locked. What is the source of this limitation? Is this typical?
Rear Locker <= 5 MPH?

Yeah its typical. Also, toyota has stamped that on e-locker vehicles for years. No need for concern. Ask the guys with pre-runner tacomas how fast they're running. 
It's more of a liability sticker than anything in my book.

The one on my tacoma goes as fast as I can go in 4 lo . Hey that rhymes!
You need to look into the grey wire mod for the taco. Then you can be locked in 4hi or 2hi. 
It's an easy mod. Took me all of 20 minutes.

Thanks. It would suck to be tooling around with the rear locker engaged and not be able to exceed 5 MPH. Are the Wranglers like this?
Fear not! Did some fun, long rutty rocky hills last weekend using A-Trac and lockers to test both. Went well over 5mph and both work great. A-Trac was pretty impressive, but its wierd to have the vehicle actually make decisions for you (you feel and hear it). C5 corvette's active handling system was similar.
I had a pre-runner trd with the rear locker and would run it pretty fast. no problems at all.
A guy at my office ran his elocker down the hwy in his 02 4runner at 55 mph for 30 mins no problems.
I heard it was 25 mph max, and then it disengages.
it seems that would be worse for it to disengage at 25mph.
Well it's obviously not 5 mph because I drove the test vehicle with it engaged at least 15 to try to get it to disengage. I'm almost sure it was 25, and it doesn't seem like it would be a problem to disengage. I can see problems with it if you were trying to lock it at 25 however.
While I run locked at pretty good speeds without problems one thing I will NOT do is cause the locker to actuate at speed. I only lock and unlock at less than 5mph. If you disengage/engage while at speed there is potential for stress to be placed on parts of the locker when only portions of the surfaces are engaged. The locker is designed to withstand loads being spread evenly across the parts when engaged fully (say the pin that slides). If only part of that pin is engaged (as in the case of sliding in or out disengaging/engaging) then only the part of that pin that is mated is carrying the full load. That could be alot to ask in certain situations.
If the FJC unlocks at 25 automatically it'd be the only yota to ever do so. I seriously doubt it does that.

Well I'm not sure if it unlocks itself at all, but it doesn't at 15 mph for sure because I tried it with the dealers demo truck.

I dont think it would be a problem to go a high speeds with a locker engaged. Think about all the trucks that have rear spools that are DDs or driven to trails.
I've driven my pickup 75+ mph on the highway with the rear spool for long distances. No issues at all...
I could be wrong but I dont think an ARB, E-locker, etc would be any different.
