Two comments: the patch at http://trac.sagemath.org/sage_trac/ticket/6218 makes arithmetic in hyperelliptic Jacobians a constant factor, about 4-5 times faster for me. It's just a few simple changes that really help. Second, I have code that should be merged in the next few iterations for computing theta functions (and their derivatives) which is the easy half Magma's analytic Jacobians package. I will eventually implement the other half (finding a homology basis and period matrix, etc) but not until much later -- if you're interested, please let me know (and preferably do it for me!).
