10 gallon batches definitely help.
Brewing often helps.
And if your pipeline is getting *too* full, brew something that takes aging time. Right now I have ~10 gallons of Belgian Golden Strong that's barrel-aging as part of a homebrew club project (ready this spring/summer), 10 gallons of apfelwein aging that will probably go on tap 5 gallons by this October and 5 gallons by the following October, 5 gallons of a collaboration imperial milk stout with a fellow brewer (ready by winter), and 5 gallons of a lager that is maturing right now and should be ready in ~5 weeks. If you're limited by the number of taps you've got, those "big" aging beers can be bottled instead. And since you're kegging, you can bottle from the keg after force-carbonating, so the beer will be clear and properly carbonated every time.
When you have those beers aging, they're like gifts to yourself to supplant your pipeline down the road. And with some of the quick-turn beers you can make now that you're kegging (i.e. 2 week grain-to-glass), you can keep things going despite having those other beers aging.
(Only one problem -- I need more corny kegs!)
