It depends on the usage. Simply broadcasting a TX or INV to a remote
peer does not require a connection, clearly... but you probably want
to signal acceptance of those messages somehow.

But other uses, like subscribing to a broadcast, does require some
notion of an association.

In the rough draft, a parallel TCP connection with version/verack
sequence is required, and you may make use of it if a connection is
needed.

But that is just one approach. A more robust, heavyweight UDP P2P
might be a hole-punching TCP alternative. It's up to the community
and results of experimentation.

Bittorrent has evolved a full transfer protocol over UDP, to get
around firewalls and the like.
