@wandeljw,
It's quite a volatile mix going on, I've no doubt that both Conservative and Liberal cabinet ministers will give an outward show of unity. The party apparatus is different though. The Liberals took a real pummelling in the local elections, and are desperate to highlight differences between themselves and the Tories. The Liberal party has been especially vocal about this, and with conference season coming up there's every chance prominent backbenchers will rip chunks out of the other party, to a cheering crowd of their own supporters.
The Liberal Conference comes first, and how supportive the party is of the Tories, and their own leader, will be the first real indication of how this coalition is faring.
The next big test is the London Mayoral elections in May. The incumbent is the Tory, Boris Johnson. He is an incredibly high profile figure, as much a TV personality as a politician. He has a very affable, bumbling persona, and attracts a lot of personal votes. He also has very serious rivalry issues with Cameron, going way back to when they were both at Oxford and, before that, Eton together.
Boris, (yes he is someone who has the status of just needing one name,) has already criticised Cameron's planned cuts to the police budget. Cameron, for sake of party unity, will have to support Boris, who may attack some aspects of government, just to prove he is his own man. If he loses, he'll probably blame Cameron, and begin positioning himself for a leadership challenge after the next election.
Intersting times indeed, but all this does not necessarily translate into support for the Labour party.
