Sage provides some level of interaction actually without any deployment made
on local side. Try for instance the following example on sagenb.org

from scipy import stats
import numpy as np
import matplotlib.pyplot as plt

@interact
def plot_gamma(a=(1,(1,10)), loc=(0,(0,10)), scale=(1,(1,10))):
    rv = stats.gamma(a, loc, scale)
    x = np.linspace(-1,20,1000)
    plt.plot(x,rv.pdf(x))
    plt.grid(True)
    plt.savefig('plt.png')
    plt.clf()

This one is very useful for educational and demonstrative purposes. Still
requires a bit Sage syntax manipulations to make things fully interacting on
browser.

Nice that you have matured IPython infra for implementing
such interactive functionality. I was thinking perhaps running something on
top GApss Engine but not sure they allow compiling/running C/C++ extensions
on their servers. Alternatively, like in Sage servers virtual OS'es might be
the way to go with it then possibly there will be user registration and
management issues (not sure about all specifics).

Probably, Ondrej might like experiencing with this idea :) Since he has
similar initiatives and asking help on similar topics. I am trying to
graduate myself working to solve some of my research problems and struggling
with writing especially to move on PhD. This might be a very fun Summer job
if I am wandering around jobless then.
