The return of dragons is of tremendous importance for Westeros, even if only Doran Martell, Euron Greyjoy and Marwyn the Mage seem to take the measure of it at the moment. It is no less important for Essos which has suffered millenia of Valyrian rule. It's likely that the news of the return of dragons elicited a strong reaction in the Free Cities. We have two hints of that in the book concerning the two Free Cities we know best, and which might be the most important.
When the Iron Banker reach the Wall, he reacts sternly at a light-hearted remark of Jon Snow
The Iron Bank in Braavos has its seat near the palace of the Sealord, a probable sign that the Bank is close to the Sealord. We have seen no sign of the reaction of Braavos to the return of dragons. (It's perhaps noteworthy that the Sealord is dying in ADwD.)
The city is ruled by a triarchy, but the aristocracy of Volantis is composed of pure-blooded descendants of the Valyrians. Aboard the Shy Maid, young Aegon recited a little history lesson to Haldon.
“Just so,” said Haldon. “And the present triarchs?” “Malaquo is a tiger, Nyessos and Doniphos are elephants.” “And what lesson can we draw from Volantene history?” “If you want to conquer the world, you best have dragons.”
In ADwD, it is expected that a large Volantene fleet is sailing to Meereen (but a close look reveals no real evidence of that). Moreover an election was taking place in Meereen during ADwD and a change of power within the triarchy is about to happen. When Arianne Martell came to see her father after her failed rebellion, Doran is playing with cyvasse pieces
A comment I took as meaning that the Volantene will not deal with Dany by brute force (and particular not simply by sending a fleet).
My impression is that the Braavosi will want to eliminate dragons and the Volantene will want to gain control of them, since they consider themselves heir to the Valyrians (Volantis, "first daughter of Valyria" etc). However, for those great powers, it seems good policy to send a company of sellswords at the center of action, and an agent of the highest quality at court to watch closely the situation. For whom really work the Windblown, Long Lances, Stormcrows, Cats, and Second Sons, I can not say.
Daario's company, the Stormcrows, has no discernable history (compare with the Second Sons, the Windblown, the Golden Company). Jorah Mormont does not know them, which is curious for a former sellsword. They claim to be a brotherhood of Free Men. But, after the end of the initial triumvirate, Daario seems to have absolute authority over them (killing his serjeants without judgement). It's easy to imagine that the murder of the two other captains of the Stormcrows by Daario was a ploy to gain Dany's trust. So I find no reason to disbelieve that the Stormcrows have hidden loyalties.
