I should mention that Jay (Lepreau) is putting together a large
distributed system testbed here consisting of 200+ StrongArm-based
machines and enough PCs acting as routers to give us a high degree of
flexibility in how we configure the system (e.g., we can introduce link
delays and error rates and such not). Jay can fill you in on the
details of the testbed, if you're interested, but one option to consider
is figuring out a way to leverage it as part of Access (or in addition
to Access).
Take care -- good to hear from you.
