I think it would be nice if it was possible to try programs online like we can do on TI-Planet, except as difference the ROM/OS would have to be provided by the user. Juju had a TI-81 Illusiat example a few months ago, but the ROM was included in the emulator so for Omnimaga it wouldn't be a good idea. For Nspire Lua programs it could maybe use the document player thing by TI or even Jimbauwen's Lua emulator.
