Hi,

Does any part of twisted support mobile Python code? Something like Pyro's Mobile Code objects? http://pyro.sourceforge.net/manual/7-features.html#mobile

I wrote out a big long screed in response to this, but then decided it was probably overly harsh.

Well, we're all grown-ups here and I think I can take it, but it's still interesting enough to know that you think it's the wrong thing. Translation -- I'll try not to be offended! :) The bottom line for me is that I noticed an easy way to do some parallelization of "embarrassingly parallel" problems which would have a nice match with the Pythonista mindset: instead of map( func, vars ), we could have a map_distributed( func, vars ), which gets mapped over many processes, potentially over many CPUs. I'm thinking now solely of a single multicore box or clusters behind firewalls, so security issues didn't seem relevant. I've got some rudimentary Pyro code working, but I was wondering what was available with Twisted.

No, Twisted does not support this. The lack of support is intentional. There are a huge number of security-related issued with doing what Pyro does, so Twisted doesn't do it.

OK.

In fact, PB goes in the other direction: even if the code defining the class of an instance passed over PB is available on both sides, it _still_ might not be accepted by the recipient, if it has not been explicitly marked as safe by the recipient.

OK, thanks. I just wanted to make sure I wasn't missing something in the spread docs...
