I’m trying to create something that looks like a lung alveolus, with a bunch of branching capillaries on the surface. I’ve been manualling creating a Bezier curve, then bevelling with a circle shape, but it sucks. Is there any other way to create branching tubules other than by manually fooling around with a bezier curve?

was the same as you have done. This for the original tube. Then convert to mesh. At the end that you want to fork reshape the loop of verts to a figure eight shape so you have two openings. The two verts in the center that you dragged towards each other, scale them together and remove doubles so you have one vert that is common to both openings. Select each opening individually and scale and grab them back to size and position. Subdivide smooth to get some verts to work with in your next fork, then extrude each one from there in their individual directions, scale, rotate, extrude, scale rotate… and repeat the branching exercise ad lib. You can use the PET to yank then around a bit.
Actually those are capillaries (so may not be what you want) alviolii look like bits of cauliflower but are rich in capillaries (so maybe they are).
