PlRPC vs POE as core P5EE Server

Hi,

There are going to be an increasing number of cases where
the P5EE needs a core server, separate from the web server.
(Similar in some respects to how an EJB server is separate
from the web server in which Servlets run.)

I am weighing the prospects of basing this on either

  * Jochen Wiedmann's PlRPC
    http://search.cpan.org/search?dist=PlRPC

  * Rocco Caputo's POE
    http://search.cpan.org/search?dist=POE
    http://poe.perl.org/

I am leaning toward the first.
(Not that both can't eventually supported, of course...)

Any thoughts from those who have experience with them?
