Cool idea!  As far as splitting on whitespace that does look like a
problem.  I hate to make assumptions about formatting on output like
this, but perhaps this rule would work: split on at least two
consecutive whitespace chars, assuming that the whitespace between
"Peer" and "User" is actually spaces on not tabs.  I don't know Python
but the Perl command would look like this:
@keys = split /\s{2,}/, $dataline;
Where @keys is an array of the split out items ('Peer','User','Caller
ID',etc.)
And $dataline is the variable containing the line to be split.
The regexp in the split function says, "Split on at least two
consecutive whitespace characters, treating all consecutive whitespace
characters as one delimiter."  (Did that make sense?)  

I noticed that the output *SEEMS* to be fixed-width, but I think you are
correct about not hard-coding the positions of the fields.  If you feel
safe making the assumption that no two fields will ever be separated by
less than two whitespace chars then splitting on the 2-or-more
whitespace chars would work.  

BTW, which AMI command returns those results?  Just curious.

P.S. - It's been a learning experience, but the Perl/POE/Asterisk client
combo has been pretty stable.  It is event-driven and non-blocking.
Email me off list and I'll be happy to show you what limited success
I've had with it thus far.
