[erlang-questions] Process migration/ Process state extraction/ injection

[Paul Barry]

Hi Tyron.

For my Masters thesis (way back in 2003), I looked at 'mobile agents'
as a technology area, and implemented a 'strategy' I came up with in
Perl.  What I did was look at how Perl's debugger handled a Perl
"process", then I used some of the debugging techniques to query the
process state, extract & bundle it all together, then ship the code &
the state to the new host... this worked reasonably well, and I was
able to prove my point.  It was/is a bit clunky, but it works!  :-)

I've an old(ish) website describing all of this here:
http://glasnost.itcarlow.ie/~scooby/

So... my suggestion would be to look at how some of Erlang's debugging
tools to see if you can attain inspiration...

Good luck.

Paul.
