Another approach could be following: when bzr compiled to standalone 
bzr.exe in standard sys module appears attribute 'frozen' with value 
'console' (because we compile it to console program). So, plugin loader 
engine could check for this attribute and search (and load) plugins 
inside bzrlib/plugins with zipimport module.

Help from people who comfortable with zipimport is very appreciated.
