Web enabled electronic circuit simulator

Does anyone want share circuit simulation data via cellphones?
Often i find that diagramming and explaining sub-circuit schematics, line is difficult.
if i have to explain an issue with a circuit, how i can share this with someone at makerspace via phone?
I the one solution that presents itself if to have some online circuit simulation. For this purposes we don’t want to have dynamically allocated memory in any web base circuit simulation, because this would present a security loop hole and would limit bower connective (aks cross platform integration via browsers).

these are the solution i currently have.

It would be nice to have something like this… may be we could bake the circuit simulator into the dallas makerspace’s talk forums.
