Ruby certainly took *much* of the best, but certainly not *all* of it. I
expect to see this great language continue to improve.

No, but there is the interesting possibility of piggybacking on
Activstate's Komodo IDE for Python and Perl:

It seems unlikely at present. I think Ruby is (for most practical
purposes) already more or less as widely available as Java, platform-wise.
The main advantage of JRuby would probably be to access Java libraries.
However, for most purposes, it probably would almost always makes more
sense technically/economically to access these directly from Java, for
unfortunate interface and support reasons. This is one of the factors that
makes C#.NET potentially intriguing--that is, *if* it turns out to
actually be reasonably well ported to non-MS platforms.

It would be nice, but it turns out to be (technically) very difficult to
serve two masters.

However, you might want to check this out and put your question to someone
more directly involved:

To some (highly qualified/limited) extent, this is somewhat true
feature-wise, but (so I've been told) the internals are radically
different.
