Ask HN: Historical Market Data for use in webapp?

I'm building a webapp that lets you practice trading. I don't really expect to make much/any money out of it and so I'm after a cheap source of daily historical market data that I'd be allowed to use in the app.

Lots of sites offer free historical data, but they appear to be for personal use only and I guess this doesn't qualify. Does anybody have experience with a supplier that lets you use the data in your own online app? (many thanks in advance!)

Haven't used their service, but this seems to be what you need: http://www.opentick.com/.

Thanks lpgauth. I scanned their faq and they mention that opentick doesn't currently allow redistribution of the data http://www.opentick.com/index.php?app=faq&event=index#b8...

I'd guess that because my planned webapp is public this would be construed as redistribution of the data - does that sound likely?

Thanks Prakash there's some useful links here, but this thread refers to somebody needing realtime data for private use. I'm after pointers to a supplier offering historical data that can be used within a public webapp.
