Features and shortcomings of html5

Yeah, you are still in for a bit of a wait for the initial load to complete but that doesn't seem to have deterred my users yet (they were pre-warned about the delay), even those who were accessing the sims from outside the university network. Not sure that I'd want to attempt to deliver it over anything less than a 4G mobile network though, and if the cost of data use is an issue for the end user then...

    Thanks Terry, that's helpful. I get the feeling that we can do almost 
    anything internal to LC's engine, but things that require a call out to 
    the OS are harder.
    
    I did a quick conversion of a simple stack way back when HTML5 was first 
    released and got pretty good results, but the load time was murderous 
    and I dropped it as unusable until it got faster. I haven't tried it 
    since that was improved, maybe it's okay now.
    
    The deal is, my client and I have fast internet connections and we're 
    willing to wait a bit for the stack to load, but if this project goes 
    through it could be used by anyone including, as she told me, "by people 
    in Nairobi" who may be on slow connections or even cell data.
    
    We're also considering writing mobile apps instead, but her customer is 
    hoping to integrate directly with their web site.
    
    At any rate, thanks for the feedback.

Multiple cards are fine but I haven't tried switching between stacks. Text display isn't that great out of the box but that shouldn't be too much of an issue unless you have pretty strict formatting requirements (you can load fonts but I'm not sure whether it's worth the trouble). The biggest drawback for me has been around networking but that seems to have been substantially improved in recent releases (I haven't had a chance to explore these yet).
