clients so they can create a proper .forward file. 2) Add some
test code for seeing how feasible it is to do accounts on ops/tips
using tmcd instead of direct ssh. Initial results are not good; too
many accounts; does not scale well. Going to need a smarter protocol
for doing hundreds of accounts, but I will leave this code in place
for now. Note, unlike testbed nodes, control nodes must connect with
ssl.
