I tried installing the N900 wordpress binary and it did run up to the splash screen, then it segfaulted.
At first it asked for some shared libraries. I copied those to the N9 from the N900 and then I the splash screen appeared.
With my little knowledge I suppose that some binaries *may* run as it was later on in the execution that the segfault appeared, it even gave me a window. So generally maybe it's a no but if the app does not use the different commands in the processor it could work. I intend to test it some more when I find some free time.
