On install of opera choose the 'advanced' option and change the default install directory to 'Profile1', 'Profile2', etc. When you enable Opera Unite services -- increment the port# for each profile, i.e, profile1 8841, profile2 8842. When you setup ~ establish the unite service -- you have to associate each profile with a unique myOpera user.
Below is another method I've tried -- I found services less stable using this method. I don't know if that's because I was running a single copy of Opera -- or because earlier version (the Unite Beta) was less stable...
Steps to replicate a profile:
1) Disable synchronization and opera unite services to profile1
2) Duplicate profile and matching 'program files':
a) Copy 'profile1', to 'profile1 - copy'
b) Rename 'profile1 - copy' to 'profile2'
c) Copy 'profile1\Opera' (under program files)
to 'Profile1\Opera - Copy'
d) Rename 'Profile1\Opera - Copy'
to 'Profile2\Opera' (to match
new copy of roaming profile).
3) Establish two different myOpera users for profile1 and profile2
4) Enable synchronization ~ opera unite services on profile1
and profile2 - with myOpera users (established step3)
5) Increment port number on Opera Unite services per each
new profile to allow independence of services
...Repeat for as many profiles as required...
Seems daunting? It is. But results are worth it.
