I've never had any problems like that. Depending on the yeast and beer, I'll do a week or 2 primary in a bucket or carboy before putting it in my secondary keg. There really is nothing going on except clearing If I'm dry hopping I'll put the hops in a bag and rack the beer in on top. Its easy to pull samples off and see when its clear or when the hoping is right.
if you listen to jamil talk about no-secondary, he is actually doing a secondary in a keg. I can't remember what ep. I think it might be one of the lager shows.
