Hi Vijay,
Let me know if I should spend time on fixing issues with Unify, instead we can get switch ported to dht, make that stable, and move unify to 'legacy/unify'. 

Please decide on this.

Regards,

Hi Amar,

We can accord lower priority to this. Let us concentrate our efforts on switch in dht and get that working. 

Regards,
Vijay

adding dependency on bug-409, once committed, we can close all unify related bugs
