We would like to target Roku 2 and Roku 3 and Marmalade supports Roku 3, Roku 2 (HD, XD and XS) and the Roku Streaming Stick, so from that perspective the Marmalade does not limit us.
Crunchyroll also uses standard Brightscript APIs (roScreen based I believe).
Ok. I'm not sure what marmalade is or isn't capable of. But if it does what your saying, then it seems like the way to go.
Just FYI though, YouTube doesn't use marmalade. Larger companies (Netflix, YouTube) are granted special access to the NDK.

Unfortunately after a debate with Marmalade support it came out that for Roku they support only C++ development: http://docs.madewithmarmalade.com/displ ... tplatforms
