To avoid removing added things in working_set ... i remove the entry for which i need to switch versions in easy-install.pth and then only 'resolve'-ing and 'add'-ing to the working_set.

I don't know if this (removing the lines in easy-install.pth) will reflect on easy_install to work properly, but for now i'm happy with this solution :)

Still will be very thankful for any comments and suggestions.

"easy_install -m projectname" will remove the line for you. For that matter, using -m when you install those eggs in the first place will also do the trick.
