Well you have to define what "secure" is for you.
Secure can mean a lot of things.

What makes you think you would lose that with Pyro?
(and not with other IPC protocols)
Pyro's goal is to make the network as transparent as possible
for the application programmer. So yes, you will be able to
access remote objects as lists etc. But it won't be very
fast if you iterate a 20,000 node list over the network.
Better grab the list as a whole over the network and iterate
the list locally.

IMHO Twisted is overkill then.
And you would still have to decide on the actual
communication protocol you'd be using...

For the kind of app that you described it seems to me as if
you wouldn't want to spend a big chunk of your development time
on the communication stuff, and about performance: does a data
entry app have to shove 50Mbit/s over the network?
