JDC>In my humble opinion probably the only part of the article that *isn't* speculation is the part where the Archive article is quoted as saying that Castle is *considering* open sourcing RO.
And that is still no more or less than *considering*. It *may* or *may not* happen.
If one were to assume that Castle *were* to open source RISC OS (and remember it's RISC OS 5 - they don't have full source for Select as parts of that are ROL's baby) your assertion that RO5 development would cease is no less speculative than the whole article.
If RO5 were open sourced programmers would be free to add to it User Interface features that parallel those in Select (without using Select Sources either). The end result would be a more portable/modern RISC OS that users could use *instead of select* and yet not lose the Select UI features yet gain all of RO5's advantages. Programmers could enhance CDFS and other bits and pieces... in short rather than having a limited development resource there would be a rather broad one supporting RO5.
The question then would be what of ROL and Select ? Indeed......
