RPC with Python - Comparison?

[Wolfgang Keller]

Hello,

has anyone done a comparison of the different RPC protocols &
implementations available for Python that is more extensive and exhaustive
than the one on
http://www-106.ibm.com/developerworks/webservices/library/ws-pyth9/?

Topics would be:

- Runtime efficiency
- Development efficiency
- Design concepts & features (security...)

Candidates could be:

- Pyro
- Twisted.spread
- OSE (XML-RPC)
- ICE
- ...others?

TIA,

Best regards

Wolfgang Keller
