Training can be anywhere from 1-3 months depending on the developers' background if you use the TPM from a 3GL. With a high level development tool it can be 2-3 weeks.  

>2. What is the cost/staffing requirements in administration?

Normal sys admin function. Plan on about 4+ weeks of learning (2 initial
plus more over time). Once the environment is up and running it isn't too
bad.  

>3. How complicated or error-proness of either of the APIs? Tricks and traps?

Nothing too unusual in the APIs -- *That's not the problem*.

Traps? Watch out for the amount of time the developers spend *not* with the
APIs but all the mechanics behind the scenes -- building and re-building servers for instance. This is where the overhead can suprise you!

Yes you can do this. You will get a slight performance overhead, which is
to be expected. Absolutely worth the overhead.

Excellent future. Don't worry about future CORBA support, it will happen
for sure. Realize that until ORBs acquire transactional support (OTS extension) and some history with it, there not suitable for heavy duty TP. This is coming -- see Transarc's web page for instance for the early
Encina/Orbix release.

Not low level, normal 3GL. You'll have encapsulated, isolated services from the start. Though not yet full OO (no polymorphism, etc.).

How fast do you make decisions? :-)

Proof of concept time is governed by learning time, again a tool helps a lot.

Brief commercial message: Take a look at our application generator, it is saving our Encina and Tuxedo customers a lot of time.
