 # The initial requirements of the kea multi-threading packet processing design:
 
-* It must not break the DHCP protocol
+* It must not break the DHCP protocol (obvious)
+* Must compile and use supported dependencies on all supported platforms (obvious)
 * It must support MySql and PgSql back-ends
 * It must be configurable in the configuration file, at run-time using control channel commands or on the command line (still in discussion).
 * It must improve the server performance with at least a factor of %% (still in discussion - best scenario: should scale linearly with the increase of thread count)
