I can feel a new thread coming on as this one is fast becoming one about the Platform SmileMods, time for a split?
To come back to what Nick Durie said, theoretical and tactical unity implies a bit more than a basic level of agreement. And for an anarchist group it sooner or later will become an issue - at what point do you draw the limits of dissent within an organisation. Do you decide that you're against national liberation struggles but let individual members argue their case publicly, for example?
Even in the broad case that you talk about - to take an example from 16 years ago (I feel old Sad ) the Poll Tax. There was theoretical unity among loads of people that it was a bad thing. On the left, there wasn't a lot of tactical unity - Militant, the DAM, the ACF, Labour Briefing - all held that non-payment backed by non-registration and non-collection were the way forward. The Stalinists only wanted to write to MPs. The SWP wanted non-collection to be the main way forward, even though they knew it didn't have a hope. Within the main thrust of the anti-PT movement, Militant tended to de-emphasise non-registration for fears that they'd lose potential voters, while us anarchists advocated it loudly because we weren't worried about disappearing off the radar of the local state. There were also major differences over orientation to the Labour Party, who were happily jailing non-payers up and down the country. Militant were in Labour at the time being witch-hunted so didn't want to make too big a thing of it. The Anarchist Workers Group (the last and unlamented Platformist group in Britain) argued at an anti-PT conference that Labour should be excluded because they were racist. Their underlying argument was correct but they blew it and disappeared into Trotskyism soon after.
If you scratch the surface of any "broad" campaign in the interests of the working class you will not find theoretical and tactical unity beyond some basic agreements. That's what is meant by it - that once an agreement has been reached members of an organisation argue for it. The WSM (bless 'em) have loads of stuff on this sort of thing on their website and it's probably worth a look as it does actually relate to the here and now rather than the situation during the Russian revolution.

By broad I mean libertarian communists. Political parties would need to be excluded. In terms of national liberation struggles certainly it wouldn't be the role of a platform to organise for them, or hold a position. If members of a clandestine platform chose in their spare time to argue for this it would have to be their thing and there would need to be rules about not piggy-backing on contacts built up by the platform.

Yes but I'm saying that _because_ I'm in favour of it! It's exactly anarcho-Trotskyist - that's what's good about it!
It's not a facile argument to state the obvious. What's facile is the rejection of organisation implied by a rejection of the platform because effectively it calls for organisation and 'front groups'.
